A restaurant needs to order 20 gallons of milk. Each gallon costs $1.79. Approximately how much will the milk cost?

Explanation:
To estimate the total, multiply the price per gallon by the number of gallons. So 1.79 dollars per gallon times 20 gallons equals 35.8 dollars. Because it says approximately, pick the option closest to 35.8. The options are 40, 18, 20, and 55; 40 is the closest to 35.8. (If you round 1.79 to 1.80 and multiply by 20, you get 36, which is still closest to 40 among the given choices.)
