Answer:
A
Step-by-step explanation:
8 gallons of regular gas with 10% and 2 gallons with 85%
8 x 10 =80%
2 x 85 =170%
170+80=250%
10 gallons each with 100%, so 10 x 100 =1000%
250% of 1000% = 1/4 or 25% ethanol
Hope this helps!

C. (Chanterelle mushrooms cost less by $0.90)
Step-by-step explanation:
Divide 11.25 by 2/3, for the total amount of pound for the Cremini.
Do the same thing for Chanterelle, but the numbers given for it.
We than find out that Cremini=16.87, and Chanterelle=15.98

Our answer is 0.89, but we will round it to 0.90.
