At an amusement park, Bill enjoys two rides on the water slide and three rides on the Ferris wheel, and it cost him $15.55. If the water slide costs $3.95, find the cost of the Ferris wheel.

$2.55

Step-by-step explanation:

Let

Cost of Water slide = x

Cost of Ferris wheel = y

Cost of Water slide = $3.95

Cost of Ferris wheel = ?

Total cost = $15.55

The equation

2x + 3y = 15.55

2(3.95) + 3y = 15.55

7.9 + 3y = 15.55

3y = 15.55 - 7.9

3y = 7.65

y = 7.65 / 3

= 2.55

y = $2.55

The cost of the Ferris wheel is $2.55
