Question

Miss Edwards bought 11.92 gallons of gasoline at $1.49 9/10

per gallon. Estimate how much she paid for the gasoline.

Answer 1

To estimate how much Miss Edwards paid for the gasoline, we can round the price per gallon to the nearest cent and the amount of gasoline to the nearest tenth of a gallon.

Rounding $1.49 9/10 to the nearest cent gives $1.50 per gallon.

Rounding 11.92 gallons to the nearest tenth gives 11.9 gallons.

So, Miss Edwards paid approximately:

$1.50/gallon × 11.9 gallons = $17.85

Therefore, an estimate of how much she paid for the gasoline is $17.85.
