the sum of 12 times a number, n, and 4 is no more than 190. What are all the possible values of the number?
Answer:
{n:n≤15.5}
Step-by-step explanation:
√First derive the inequality from interpreting the statement,thus 12n+4≤190
√Second, solve the derived inequality ( ie.make n the subject)
√Finally, you'll arrive at the answer as n≤15.5
Therefore the possible values of the variable n is all numbers less than or equal to 15.5
PROOF
For n greater than 15.5
Let's take n to be 20
Therefore from the derived inequality
12n+4≤190
12(20)+4 = 240
Here,240 is greater than 190
Since for n≥15.5 will not satisfy the inequality n≠all numbers more than 15.5

PLEASE ANSWER At the city museum, child admission is $5.70 and adult admission is $9.30 . On Saturday, 155 tickets were sold for a total sales of $1200.30 . How many adult tickets were sold that day?
Answer:
88
Step-by-step explanation:
x = # of tickets for children
y = # of adult tickets
5.7x + 9.3y = 1200.3
x + y = 155
y = 155 - x
5.7x + 9.3(155 - x) = 1200.3
5.7x + 1441.5 - 9.3x = 1200.3
-3.6x = -241.2
x = 67
we want y
x + y = 155
67 + y = 155
y = 88
