Question

Lisa bought 8 doughnuts at the cost of $ 5.50 for a dozen.

� �How much did Lisa have to pay?

Answer 1

8 x 5.5/12 = 2x5.5/3 = 11/3 = $3.67 rounded off to nearest cent

$5.50 for a dozen means each donut costs 1/12 of $5.50 = 5.5/12

multiply that by 8: 8(5.5)/12 = (8/12)5.5 = (2/3)5.5) = 11/3 = $3.66.666...
