Re: A car got 33 miles per gallon using gasoline that cost $2.95 [#permalink] 08 Jan 2017, 09:17 2 This post received KUDOS Expert's post Explanation Scanning the answer choices indicates that you can do at least some estimation and still answer confidently. The car used $$\frac{350}{33}$$ gallons of gasoline, so the cost was $$(\frac{350}{33}) \times 2.95 dollars$$. You can estimate the product $$(\frac{350}{33}) \times 2.9$$ by estimating $$\frac{350}{33}$$ a little low, 10, and estimating 2.95 a little high, 3, to get approximately $$10 \times 3 = 30$$ dollars. You can also use the calculator to compute a more exact answer and then round the answer to the nearest 10 dollars, as suggested by the answer choices. The calculator yields the decimal $$31.287....$$ . which rounds to 30 dollars. Thus, the correct answer is Choice C,$30.

Explanation

We do have 33 = 1 gallon and 350 miles = x gallons

Cross multiply and we have $$\frac{350}{33} = 10.6$$ gallons

1 gallon is about 3.00 $* 10.6 we do have 31 C is the answer _________________ Need Practice? 20 Free GRE Quant Tests available for free with 20 Kudos GRE Prep Club Members of the Month: Each member of the month will get three months free access of GRE Prep Club tests.

I legit just used the calculator for this one and did (350/33)*2.95 = 10.606*2.95 = 31.28 and rounded that down to $30. Re: A car got 33 miles per gallon using gasoline that cost$2.95   [#permalink] 29 May 2020, 08:52
