Patrick bought 54 inches of material that cost $3.40 for one. Yard. What change did he get if he paid for the material with $20 bill?

Patrick got a change of $14.90 for paying for the material with a $20 bill.

Explanation:

1 yard of material costs $3.40. Patrick bought 54 inches of material.                                                                                                 First, we must convert the inches into yards. We have 36 inches = 1 yard.                                                                               To calculate how many yards 54 inches we divide the 54 by the 36.                                                                                                        So 54 inches of material = 54 / 36 yards = 1.5 yards of materialSince 1 yard of material costs $3.40,                                         the cost of 1.5 yards of material = 1.5 × $3.40 = $5.10.         Patrick paid for the material with a $20 bill. So                               the change Patrick got = $20 - $5.10 = $14.90.

Subtracting is the opposite of adding

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.

the answer is 18.
