A school sold 51 less children’s tickets than
adult tickets for the school play. Adult
tickets cost $1.25 and children’s tickets
cost $0.75. A total of $129.75 was taken
in. How many of each kind were sold?
Given:
The school sold 51 less children's ticket
Adult costs $1.25 and children’s tickets cost $0.75
A total of $129.75 was taken in
Each kind of ticket sold is calculated,
Solution:
We are considering the ticket costs,
1.25x + 0.75 (x-51) = 129.75
Changing the terms from decimals to whole numbers,
125x + 75 (x-51) = 12975
125x + 75x - 3825 = 12975
200x - 3825 = 12975
200x = 16800
x = 16800/200
x = 84
So, 84 adult tickets were sold.
