The equation is (11.50 + x) * (1 + 5%) = 16.80 and the solution is $4.50

How to write and solve an equation to find the cost of the cat food?

The given parameters are

Cat litter = $11.50

Cat food = x

Sales tax = 5%

Total =16.80

The equation is then represented as

(Cat litter + Cat food) * (1 + Sales tax) = Total

So, we have

(11.50 + x) * (1 + 5%) = 16.80

Divide both sides by (1 + 5%)

11.50 + x  = 16

Evaluate the like terms

x = 4.50

Hence, the equation is (11.50 + x) * (1 + 5%) = 16.80 and the solution is $4.50
