49.47 un² is your final answer since you are supposed to round to the tenths place. I hope this helps.
Answer:
$1.30
Step-by-step explanation:
If 8 chicken wings is $10.40, to find the amount per chicken wing $10.40 gets divided by 8.
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.
