Well what are her earnings to begin with ?
Answer:
9 dollars
Step-by-step explanation:
Solve with a system of equations
Let adult tickets be a and student tickets be s
1. 8a + 13s = 176
2. 4a + 4s = 68
3. s = 17 - a
Equation 2 is friendlier, so let's divide all the numbers by 4.
a + s = 17
Equation is s = 17 - a
Substitute s in equation 1
8a + 13(17-a) = 176
8a + 221 - 13a = 176
221 - 5a = 176
5a = 45
a = 9
The price of an adult ticket is 9 dollars
