Mary has y yards of fabric. She used 2 yards to sew a skirt. She used the remaining fabric to make 5 jackets

A. Find the amount of material that was used to make each jacket in terms of y.

let x = the material to make 1 jacket

2 + 5x = y

x = (1/5)(y - 2)

B. If she has 17 yards of fabric. How much material was used for each jacket?

if y = 17 yd we find x = (1/5)(17 - 2) that is x = 3 yd was used for each jacket.

A magazine costs half as much as a book. The book costs p dollars. A pen costs $2 more than the magazine.

the magazine cost: (1/2)p

the book costs: p

the pen costs: 2 + (1/2)p

A. How much does the pen costs in terms of p?

the pen costs: 2 + (1/2)p

B. If the book costs $5, how much does the pen cost?

p = $5

we plug the value for p in 2 + (1/2)p:

2 + (1/2)*5 = $4.5

the pen costs $4.5.
