Question

Emily is entering a bicycle race for charity. Her mother pledges $0.80 for every 0.25 mile she bikes. If Emily bikes 8 miles, how much will her mother donate?

Answer 1

$25.60

Explanation:

0.25 miles = $0.80

Multiply by 4 on both sides to get $/mile

0.25(4) = $0.80(4)

1 mile = $3.20

Multiply by 8 (miles)

1(8) = $3.20(8)

8 miles = 25.6

If Emily bikes 8 miles, her mother will donate $25.60

Hope this helps :)
