Question

Seventeen members of Troy's family are going to an amusement park during the week of their family reunion. Adult tickets cost $39.50 each and child tickets cost $31 each. If the total cost for admission to the part is $578, how many adults went to the park?

Answer 1

6 adults - 6*39.50= 237
11 kids. - 11*31= 341

341 + 237 = 578

Answer 2

Hello,
So the equation is 39.50x + 31y= 578

So first x has to be number of children and y be number of adults so ; x+y = 17 31x+ 39.50y = 578 x=11 , y=6.

The answer is Y=6.
