Question

Amy has $800 saved but withdraws $80 per week for gas and groceries​

Answer 1

Answer:

800-80w.

800-80(2)=800-160=640 left in 2 weeks.

800-80(3)=800-240=560

800-80(5)=800-400=400

800-80(7)=800-560=240

800-80(10)= 0. She has 10 weeks until all of her money is gone

Function: 800-80w

Range: 460
