On a certain hot summers day, 672 people used the public swimming pool. The daily prices are $1.50 for children and 2.50 for adults. The receipts for admission totaled $1289.00. How many children and how many adults swam at the public pool that day?

Answers

Answer 1
Adults = 281
Children = 391

We have two equations: number of people and money. I’ll use a for adults, c for children.

a + c = 672
2.5a + 1.5c = 1289

First we’ll solve for number of adults in terms of c
a = 672-c

Then drop that expression into the second equation to solve for a numerical value for c

2.5(672-c) + 1.5c = 1289
1680 - 2.5c + 1.5c = 1289
-c = -391
c = 391

Now put that into the first equation to get a numerical value for a

a + 391 = 672
a = 281

Checking the math:
2.5(281) + 1.5(391)
= 702.5 + 586.5
= $1289

How can you check that k ≥ 11 is the solution set to the inequality k + 14 ≥ 25?

Answers

Answer:

K= 11

Step-by-step explanation:

You solve for K by subtracting 14 by 25.

25-14= 11

When k is pluged into k[tex]\geq[/tex] 11 the statement is true because it is equal to 11.

When plugged into k+14[tex]\geq[/tex]25;

11+14 =25.

That statement is also true because 25 is equel to 25.
