Yahshua bought 4 sweaters that each cost the same amount and 1 shirt that cost $20. The items he bought coast a total of $160 before tax was added. What was the cost of each sweater. CREATE AN EQUATION AND SOLVE.

Respuesta :

If x is the cost of one sweater, then, based on the given information you can write:

4x + 20 = 160 the cost of 4 sweaters is 4x, plus $20 is equal to $160

Solve the previous equation as follow:

4x + 20 = 160 subtract 20 both sides and simplify

4x = 160 - 20

4x = 140 divide by 4 both sides and simplify

x = 140/4

x = 35

Hence, the cost of one sweater is $35
