**Bonny's truck has a fuel tank which holds 50 gallons, and she typically drives 425 miles on a full tank.**

She has added a second tank, which holds 30 gallons.

To figure how far she can go between fill-ups now, she multiplies 50 x 425, then divides by 30, to get 708.3 miles.

Is this correct?

A) Yes.

B) No she should have multiplied 425 by 30 + 50.

C) No she should have divided 425 by 50, then multiplied by 80.

D) No she should have divided 50 by 30, then multiplied that by 425.

**Answer**

Firstly, let's solve the question.

50 gallons : 425 miles 30 gallons : x miles You can use cross multiplication, but I personally prefer ratios because they make more sense in my head.

50 : 425 simplified is 1 : 8.5 To find the miles for 30 gallons, each side is multiplied by 30 30 : 255 30*425=12,750 12,750/50= 255 255+425=680 miles, which is the total distance she can travel without refilling.

A) Her answer isn't 680, so this isn't your answer

B) 425*30= 12,750 + 50 = 12,800 (Wrong)

C) 425/50 = 8.5*80 = 680 (Correct)

D) 50/30 = 1.6 recurring*425 = 708.3 recurring (Wrong) I'm not sure where those numbers came from, but the only option that gives the correct answer is C.
