Answer:
3 gallons of paint
$29.75
20%
Explanation:
1. Let's break this down:
1/2 gallon of paint covers 1/6 of his wall.
This means that we have to multiply 1/2 by 6, as there would be 6 1/2 gallon sections of his wall.
1/2·6=3
So, Jamel needs 3 gallons of paint.
2. If a pair of shoes has an original price of $35 but it on sale for 15%, we have to first find how much it's now on sale for:
15/100·35
=0.15·35
=5.25
This is the how much it's off, so subtract 5.25 from 35
35-5.25=$29.75
The shoes have a sale price of $29.75
Even though you said this was wrong, you may have to put a dollar sign in front of it.
3. This is worded a little, but assuming:
1 swimming pass is $6, 3 people buy the swimming pass, and the total cost for the 3 passes in total is $14.40, we have to find out the discount.
So, originally, before the discount, the total amount for the 3 swimming passes would've been $18, but there's been a discount and now they only had to pay $14.40.
To solve, we do the following:
subtract the original price by the sale price
18-14.40=3.6
divide by the original price
3.6/18=0.2
multiply by 100 to get into percent
0.2x100=20%
This means that A is the correct choice.
Hope this helps! :)
