A traveling circus with thrill rides charges $9 for admission plus $1.25 for each ride you take. Let r be the number of rides you take. The equation describing the total amount you will pay, T, is T = 1.25r + 9. If you pay $17.75 total, how many rides did you take?
a) 6 rides
b) 7 rides
c) 8 rides
d) 9 rides

Respuesta :

Answer:

b) 7 rides

Step-by-step explanation:

  1. Sub 17.75 into the equation: 17.75 = 1.25r + 9
  2. Subtract 9 from both sides: 8.75 = 1.25r
  3. Divide 1.25 from both sides 7 = r
  4. So the number of rides taken is 7.
