Cathy has $100 saved to spend on clothes. She wants to purchase a winter jacket for $40 and some sweaters that cost $20 each.

How many sweaters can Cathy buy? Write an inequality that represents this situation. Then solve the inequality.​

Respuesta :

40+20x=100
100-40=60
So she has $60 left, and 60/20 is 3, so she can buy 3 sweaters.
