Let c represent the admission price for 1 child
Let a represent the admission price for 1 adult
On Monday, the pool had 23 children and 39 adults, which brought in $202
This can be represented as
23c + 39a = 202________________equation(1)
On Tuesday, 25 children and 44 adults came to the pool, which brought in $226
This can be represented as
25c + 44a = 226________________equation(2)
We are asked to solve the equations using elimination Method.
23c + 39a = 202________________equation(1)
25c + 44a = 226________________equation(2)
Let us eliminate c
Multiply equation (1) by 25 and equation (2) by 23
We have
575c + 975a = 5050_________equation (3)
575c + 1012a = 5198__________equation (4)
Subtract equation (4) from equation (3)
-37a = -148
Divide both sides by -37

Substitute a = 4 into equation (1)
23c + 39a = 202
23c + 39(4) = 202
23c + 156 = 202
23c = 202 - 156
23c = 46
Divided both sides by 23

Hence, a = 4, c = 2
The admission price for children is $2 while that of adults is $4
