Question

. Tony works at a bike store. Tony earns $300 every week plus $15 for every bike that he sells. Write an inequality that can be used to determine the number of bikes (b) Tony must sell in one week if he wants to earn a minimum of $500 for that week.

Answer 1

Well seeing that he already gets 300 he only needs to make 200 so do 200 divided by 15 which would equal 13.33 repeating so if he sold 14 bikes he would have $210  300 + 15(b)=500 1st step 500-300=200 2nd step 200/15=13.33 round to 14 step 3 14x15=210 so he would need to sell 14 bikes
