Question

Bicycle city makes custom bicycles. They charge $160 plus $80 for each day that it takes to build the bicycle. If you have $480 to spend on your new bicycle, how many days can it take Bicycle City to build the bike?

Answer 1

160+80d≤480 subtract 160 from both sides

80d≤320 divide both sides by 80

d≤4

So the maximum number of days it can take them to build the bicycle so that $480 will cover the cost.

Answer 2

It would take Bicycle City 4 days to build the bike
