Maya has $15 to spend. She spent $5.50, including tax, to buy a notebook. She needs to save $7.75, but she wants to buy a snack. If cookies cost $0.25 per package including tax, what inequality would show the maximum number of packages that Maya can buy? Solve your inequality by showing your work and steps.

Maya has $15 to spend. She spent $5.50, including tax, to buy a notebook

$9.50 left

15-5.50=19/2=9.5

9.50-7.75=7/4=$1.75

She can spen $1 and 75¢ on the cookies

1.75/.25=7

She can buy up to 7 packs of cookies and still have $7 and 75¢ left

She has  15  - 5.50  =  9.50  left  after she buys the notebook

 

She needs to save  7.75

 

So....she can spend    9.50 - 7.75  =  1.75

 

So.....let N be the max number of packages of cookies she can buy  and we have that

 

 .25N   ≤    1.75      divide both sides by .25

 

N ≤ 1.25 /.25

 

N ≤  7

 

She can buy up to  7 packages of cookies

 

 

cool cool cool
