Step-by-step explanation:
Answer:
-11 for the first one and 0 for the second one
Step-by-step explanation:
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.
