roberta needs ribbon for a craft project. the ribbon sells for $3.75 per yard. whats the cost in dollars for 48 inches of ribbon ?

Question

anonymous · Answer

1 yd = 36 inches.

36/3.75 = 48/x (36 inches to 3.75 = 48 inches to x$) cross multiply
(36)(x) = (3.75)(48)
36x = 180
x = 180/36
x = 5

If I did this correctly, it would cost $ 5.00. You might need to get a second opinion just to be sure.

inches to yards are not common measures; we have to convert yards to inches.

3 feet in a yard, 12 inches in a foot.  12*3 = 36 inches in a yard

3.75 per yards is also 3.75 per 36 inches.

times that by 48 inches

$$\frac{$3.75}{36\cancel{in}}*\frac{42\cancel{in}}{1}=$$$$$
