At a fun park, the cost of a rollercoaster ride and a ferris wheel ride is $10. The cost of a Gravitron ride and a Ferris wheel ride is $12. The cost of a rollercoaster ride and a Gravitron ride is $14. What is the cost of each ride?

r = cost of rollercoaster = 6

f = cost of ferris wheel=4

g = cost of graviton=8

Step-by-step explanation:

r = cost of rollercoaster

f = cost of ferris wheel

g = cost of graviton

r+f = 10

g+f = 12

r+g = 14

Take the third equation and subtract the first equation

r+g =14

-r-f = -10

g-f = 4

Take this and add it to the second equation

g-f = 4

g+f = 12

2g = 16

Divide by 2

g = 8

Now find f

g+f = 12

8+f = 12

f = 12-8

f=4

Now find r

r+g =14

r+8 =14

r = 14-8

r = 6
