When devon cashed a $450 check at the bank, the teller gave him 18 bills, all $20 bills and $50 bills. which system of equations can be used to find how many of each type of bill devon received? a) f- t = 18; 50f + 20t =450 b) f + t = 18; 50f + 20t = 450 c) f + t = 450; 50f + 20t = 18 d) f + t = 18; 50f - 20t =4 50

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.

if you're trying to figure out how much each ounce cost it would be 0.20

cents each ounce

(2,6)
