Question

On a hot summers day 262 people used the public swimming pool. The daily prices are 1.50 for children and 2.00 for adults. The receipts for admission totalled 470.00. How many children and how many adults swam st the pool that day?

Answer 1

• 154 adults
• 108 children

Explanation:

Let x represent the number of adults who swam at the pool. Then (262-x) is the number of children. Multiplying these numbers by the corresponding admission charge will give the associated receipts. We are given the total of receipts, so we can write the equation ...

... 2.00x +1.50(262-x) = 470.00

... 0.50x +393.00 = 470.00 . . . . . simplify

... 0.50x = 77.00 . . . . . . . . . . . . . . .subtract 393

... 77.00/0.50 = x = 154 . . . . . . . . . divide by the coefficient of x

... (262-x) = 108 . . . . . . . . . . . . . . . .find the number of children admitted
