Fiona has $18 to spend. she spent $4.25, including tax, to buy a notebook. she needs to save $9.75, but she wants to buy a snack. if crackers cost $0.50 per package including tax, what inequality would show the maximum number of packages that fiona can buy? solve your inequality by showing your work and steps.

13.75 more than or equal to 0.5x + 9.75
13.75/>0.5x+9.75
4/>0.5x
x/>8
Fiona can buy at most 8 packages of crackers

First, you would need to determine how much money Fiona has available to spend... The equation below represents this. 
$18 - ($4.25 + $9.75) = $4

Next, you would need to create an equation to figure out how many packages she can buy.
$4.00 ÷ $0.50 

Now, all you would need to do is solve it. 
$4.00 ÷ $0.50  = 8

Fiona can buy 8 packages of crackers. 

I hope this helps!
