Correct adult tickets x = 72
Step-by-step explanation:
Given:
x = ? number of the adult tickets
y = ? number of the senior tickets
12$ adult ticket price
8$ senior ticket price
We will solve this problem using a system of two equations with two variables
x + y = 98 we will multiply whole equation with number - 2 and get:
- 2 x - 2 y = - 196
12 x + 8 y = 1072 we will divide the whole equation by the number 4 and get:
3 x + 2 y = 268
- 2 x - 2 y = - 196
we will now add the first equation to the second and get:
3 x - 2 x = 268 - 196
x = 72
x + y = 98 ⇒ 72 + y = 98 ⇒ y = 98 - 72 = 26
y = 26
God is with you!!!
