You are going to an amusement park. It costs $10 to get in and $3 for each ride, r. Which of the following algebraic expressions represents the above scenario?÷

1.25a + 8 ≤ 40 (the rides and admission have to be no more than the $40 you bring in)

So now all we have to do is isolate a. Start by subtracting 8 from both sides:
1.25a + 8 - 8 ≤ 40 - 8
1.25a ≤ 32

Now divide by 1.25:
1.25a / 1.25 ≤ 32 / 1.25

a ≤ 32/1.25
Solve the above, and if you have a fraction/decimal/remainder left, remember to round down because, after all, you can't ride only part of an attraction.
