Tex book bought 20 country and western tapes last week. The regular price is 9$ per tape but last week they were on sail at 2 for $12.50. How much did tex save by buying the tapes on sale

Question

I really need help with this very much so can someone help me out with this kind of stuff

Answer 1

Diego, they asked “how much did Tex save?” “Saved” means that he paid less on sale than he would have paid at regular price.

So what you want to do is ask yourself three questions:

1) how much did all 20 tapes cost before the sale?

2) how much did he pay, on sale

3) how much less did he pay?

For question 1), there were 20 tapes at $9 each, so they cost

20 * $9. How much is that?

For question 2), there were 20 tapes, but for every pair of 2 tapes, he only paid $12.50. So, how many pairs were there? 20 / 2 = 10 pairs. So he paid

10 * $12.50. How much is that?

For question 3), subtract the answer for question 2 from the answer for question 1. How much is that?

That’s your answer.

Answer 2

Assuming that there is no difference between the price of the different types of tapes:

Regular: 20 tapes * $9/(1 tape) = $180

Sale: 20 tapes * $12.50/(2 tapes) = $125

Tex saved $180-$125 = $55
