Question

Kedwin has $150.00 and wants to buy a new pair of headphones that cost $175.00 plus 10% shipping. He decides to wait until the headphones go on sale. What is the smallest sale rate that he needs to be able to afford them?

Answer 1

He needs to wait for a 30% discount (or more)

Explanation:

175x110%=192.5

So that's how much it originally costs.

192.5x70%=134.75

134.75x110%= 148.225 (since you also need to add in shipping)
