Sue bought 3.5 yards of material at $8.70 per
yard and 5 yards of lace trim. She spent $32.90 in
total. Calculate the cost of 1 yard of lace trim.

$.49

step explanation:

Sue bought 3.5 yards of material at $8.70 per yard (3.5x8.70=30.45)

Sue also bought 5 yards of lace trim.

Her total was 32.90 and we want to find out how much the lace trim cost.

We will subtract the initial material to get the subtotal cost for just the lace trim. (32.90-30.45=2.45)

5 yards of lace trim total up to $2.45. To get how much each yard cost we will divide (2.45÷5=.49)

Each yard of lace trim costs $.49 cents
