Answer 1

Question:

Fatima plans to spend at $15 and at most $20 on sketch pads and pencils. If she buys 2 sketch pads, how many pencils can she buy while staying in her price range.

Solution:

Cost of sketch pad = $3.25

cost of pencil = $0.75

2 sketch pads cost $2 × \$3.25$ which is $6.50,

Maximum amount left = $20 - $6.50 = $13.50

Minimum amount left = $15 - $6.50 = $8.50

Maximum number of pencils that can be bought = $\dfrac{\$ 13.50}{\$0.75}$ = 18 pencils

Minimum number of pencils that can be bought = $\dfrac{\$ 8.50}{\$0.75}$ = 11.3 pencils

$\therefore$ for Fatima to remain in her price range, she can buy 12 to 18 pencils.
