Mary is making 5 mathing pillows. She needs 120 cm of braid to trim each pillow. If the braid costs $3.98 per yard, how much will she spend to trim the pillows,

Question

how do I solve the problem

Answer 1

Mark is right on, except at the last, I think you need to multiply that result by five to get the cost for all the pillows (also, too many significant figures in the conversion, but that is probably okay here :) ).

 

So the total should be $5.22 per pillow * 5 pillows = $26.10

Answer 2

1 cm = 0.393701 in

120 cm = 47.24412 in             calculate 120 cm in inches

47.24412 in / 36 = 1.3123 yd   calculate yards (inches / 36)

1.3123 · $3.98 = $5.223          calculate spent (yards times cost)
