Let p be the number of pencils Fatima can buy.

The total cost of the 2 sketch pads and p pencils is:

2(3.25) + p(0.75) = 6.50 + 0.75p

Since Fatima plans to spend at least $15 and at most $20, then we can write the inequality:

15 ≤ 6.50 + 0.75p ≤ 20

Subtract 6.50 from each member:

8.50 ≤ 0.75p ≤ 13.50

divide each member by 0.75:

11.33 ≤ p ≤ 18

Because Fatima cannot buy a fractional number of pencil, then she can buy 12 to 18 pencils.
