Evan filled up his car with 18.2 gallons of gas at $2.89 per gallon. using estimation, was he able to fill his car for less than $55.00? yes or no, and why?

Multiply 18.2 by $2.89/gallon

18.2 * $2.89= $52.598 exact amount

Estimate by rounding 18.2 to 18 and round $2.89 to $3.00 and multiply the rounded (estimated) numbers.

18 * $3= $54 estimated

The estimated amount is still close to the exact amount and is lower than $55.

ANSWER: Yes, he was able to fill his car for under $55 because it only takes $54 to fill when using estimation. We rounded gallons to 18 and rounded price per gallon to $3.

Hope this helps! :)
