You buy a container of cat litter for $11.50 and a bag of cat food for x dollars. The total purchase is $16.80, which includes 5% sales tax. Write and solve an equation to find the cost of the cat food.

4.46  

Step-by-step explanation:

(11.5 + x) + 5% = 16.8

11.5 + x = 16.8 - 5%

x = (16.8 - 5% ) - 11.5

x = 15.96 - 11.5

x = 4.46  

$4.46

Step-by-step explanation:

11.50+x=16.80-16.80×(5/100)

or, x=15.96-11.50=$4.46
