Mae Ling earns a weekly salary of $310 plus a 7.5% commission on sales at a gift shop. How much would she make in a work week if she sold $4,700 worth of merchandise?
someone please answer ASAP i'll give brainlist to the best answer <3
Answer: 662.50 dollars
==========================================================
Explanation:
If she doesn't sell a single thing, she still earns the base weekly salary of $310. This is the smallest amount she can earn per week.
If she does make sales, then she'll earn an additional 0.075x dollars where x is the amount of sales made (the total value of the merchandise). The 0.075 is the decimal form of 7.5%
In total, she makes 0.075x+310 dollars per week. In this case, she sold x = 4700 dollars worth of goods, which means,
0.075x+310 = 0.075*4700+310 = 662.50
She earned 662.50 dollars for that week.

WITHOUT WORKOUT IS ACCEPTED
Answer:
the answer would actually be 38 but thats one of the choices so the closest would be 34
not one of the Step-by-step explanation:
the angle across the one which is 128 degrees is also 128 degrees. but it is split into two. and one of the angle which is split into is 90 degrees. we know this by the little box. and to get the value of the other angle we would have to do this:
128 - 90 = 38
but 38 isnt one of the choices so i guess put 34

2.25 cubic units
Step-by-step explanation:
3 x 6 half cubes = 18 half cubes
one cubic unit =1/8 cubic units
18/8=2.25 cubic units
Answer:
12.
Step-by-step explanation:
18 ÷ 1 1/2 = 12.
There are 18 half cubes total. It is 18 divided by 1 and a 1/2 equals 12 which is eighteen divided by one and a half equals twelve.
18 divided by 1 1/2 = 12.

Quickly help me! This isn't live or anything, I just don't want to wait an hour.
Answer:
1/12
Step-by-step explanation:
When you add or subtract fractions, you need a common denominator.
Let's use the least common denominator of 12, 6, and 3.
Since 12 is a multiple of 6 and 3, the LCD is 12.
7/12 - 1/6 - 1/3 = 7/12 - 2/12 - 4/12 = 5/12 - 4/12 = 1/12
Answer:
1/12
Step-by-step explanation:
When you add or subtract fractions, you need a common denominator.
Let's use the least common denominator of 12, 6, and 3.
Since 12 is a multiple of 6 and 3, the LCD is 12.
7/12 - 1/6 - 1/3 = 7/12 - 2/12 - 4/12 = 5/12 - 4/12 = 1/12
36 is what percentage of 128?
A.
B. 28 %
C. 28.125 %
D. 4,608%
Answer:
C is the correct answer:
Solution for 36 is what percent of 128:To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 128 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 128, so we can write it down as 100%=128.
4. We know, that x% equals 36 of the output value, so we can write it down as x%=36.
5. Now we have two simple equations:
1) 100%=128
2) x%=36
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=128/36
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 36 is what percent of 128
100%/x%=128/36
(100/x)*x=(128/36)*x - we multiply both sides of the equation by x
100=3.55555555556*x - we divide both sides of the equation by (3.55555555556) to get x
100/3.55555555556=x
28.125=x
x=28.125
now we have:36 is 28.125% of 128

6) Write a system of linear inequalities that is given by the following graph.
Answer:
The system of inequalities are x - y < 1 and y < - 2 The horizontal line shown in the graph has equation y = - 2 {As it is parallel to x-axis} Now, this line is dotted and the lower portion of the graph is shaded. So, the inequality will be y < - 2 ......... (1) Again, another line is there in the graph which passes through the points (1,0) and (0,-1)So, its equation will be
⇒ y + 1 = x ⇒ x - y = 1 Now, the origin (0,0) is within shaded zone of the inequality and putting x = 0 and y = 0, we get 0 - 0 < 1 So, the equation of the inequality is x - y < 1 {As the line is dotted} Therefore, the system of inequalities are x - y < 1 and y < - 2 (Answer)

A box contains 6 red marbles, 4 green marbles, 3 blue marbles, and 2 yellow marbles. If Greg chooses one marble at random 300 times, how many times would he expect the marble to be blue?
Answer:
[tex]60[/tex] times
Step-by-step explanation:
There are [tex]6+4+3+2=15[/tex] marbles in total. Out of those, [tex]3[/tex] are blue, so the probability of pulling a blue marble is [tex]\frac{3}{15}=\frac{1}{5}[/tex]. However, this is only the probability of pulling a blue marble when [tex]1[/tex] marble is pulled at random. Therefore, we can expect a blue marble to be pulled [tex]\frac{1}{5}*300=60[/tex] times if [tex]1[/tex] marble is pulled [tex]300[/tex] times at random. Hope this helps!
