Question

Emily is entering a bicycle race for charity. Her mother pledges $0.40 for every 0.25 mile she bikes. If Emily bikes 15 miles, how much will her mother donate?

Answer 1

Set it into proportions.

$0.40/0.25 miles = x/15 miles

And then solve the proportion.

0.25*x = 0.40*15

0.25x = 6

0.25x/0.25 = 6/0.25

x=24

Therefore, Emily's mother donates $24 if she bikes 15 miles.

Answer 2

Emily mom pays $24 if she rides 15 miles
