Matt is going to walk in a fundraiser event to raise money for his school band. His mother has agree to donate $8 to the school for each mile that Matt walks, plus an additional $100. The function f(x)=8x+100 represents the total money Matt will raise dependent upon the number of miles (x) that Matt will walk.

Answer 1

Part A: $212 Part B: 25 miles

Explanation:

f(x)=Total amount earned

x=miles walked

Part A:

f(x)=8x+100

f(14)=8(14)+100

f(14)=212

$212

Part B:

f(x)=8x+100

300=8x+100

-100 -100

200=8x

8 8

25=x

25 miles
