Question

5) Derek was surfing through the internet for a good deal on t-shirts. Help Derek find the

best buy among the following deals: Three t-shirts for $28.95, four t-shirts priced at
$39, and an offer of five t-shirts for $49.95.

Answer 1

The first one

Explanation:

To figure out which one is the best deal, for each one how much one t-shirt costs.

First deal:

3 t-shirts for $28.95

To figure out how much money one t-shirt would cost, you divide $28.95 by 3.

1 t-shirt = 28.95/3 = $9.65.

Second deal:

4 t-shirts for $39

Same thing as the last one, except since there are 4 t-shirts you divide $39 by 4.

1 t-shirt = 39/4 = $9.75

Third deal:

5 t-shirts for $49.95

This time you will divide 49.95 by 5.

1 t-shirt = 49.95/5 = $9.99

The last step is to compare the three deals, and since you are trying to find the one that costs the least you can see that the first deal is the best one, because $9.65 per shirt is cheaper than $9.75 and $9.99
