B. 276.75

C. 1.83

D. 18.3

Answer 1

The answer to this math question is B

Answer 2

Option (B) 276.75

Explanation:

Distance covered by Sara in 3.2 gallons of gas is 72 miles.

So, distance covered by Sara in 1 gallon of gas is
`(72)/(3.2)` miles

Now, we need to find the total distance covered by Sara in 12.3 gallons of gas, to find we need to multiply 12.3 and the distance covered in 1 gallon.

So, distance covered in 12.3 gallons of gas

`=(72)/(3.2)* 12.3`

`=(720)/(32)* (123)/(10)`

`=(72* 123)/(32)`

`=276.75` gallons

Hence, option (B) is correct.
