Answer:
14 children
Step-by-step explanation:
Let y be number of children.
Let T be the total cost for the party.
The recreation center offers a children’s birthday party for $75 plus $5 for each child. This implies that:
T = 75 + 5y
The total cost for Payton’s birthday party is $145. We can find the number of children(y) present by doing the following:
T = 75 + 5y
But T = 145
145 = 75 — 5y
Collect like terms
145 — 75 = 5y
70 = 5y
Divide both side by the coefficient of y i.e 5
y = 70/5
y = 14
Therefore, there are 14 children present at Payton’s birthday party
