A student bought shoes online. The total cost, t, of the pairs of shoes, s, can be found by the equation below. If the student spent $569.73 on shoes how many pairs did he buy? t=61s+20.73

Respuesta :

Answer:

9

Step-by-step explanation:

t= 61s + 20.73

569.73 = 61s + 20.73

569.73-20.73 = 61s

549 = 61s

s = 549/61

s = 9
