Problema Solution

A ski resort charges $80 for adult all-day passes and $35 for children's all-day passes. On a particular day, they made $46,155 in sales. They also know that they sold 690 passes altogether. This means they must have sold

adult passes and

children's passes.

Answer provided by our tutors

Let

a = the number of adult passes

c = the number of children passes

There are 690 passes sold means:

a + c = 690

The total money earned from sales is $46,155:

80a + 35c = 46155

We have the following system of equations:

a + c = 690

80a + 35c = 46155
