Shawn sells used bicycles. he makes $120 per week plus $10 for each bicycle sold. he wants to earn at least $400 per week. how many bicycles must he sell each week to accomplish this?

*need writing the inequality! *

28 bicycles

Step-by-step explanation:

In one week he will earn $120. This is guaranteed if he goes to work and is therefore the constant.

let x be the number of bicycles sold

P(x) = 10x + 120

400 = 10x + 120

280 = 10x

x = 28

He needs to sell 28 bicycles to earn $400 each week. He needs to sell ≥28 bicycles.

9 x 8 divided by (5-3)=36
