Question 1

What percentage of 500 is 65?

Accepted Answer

13

Answer

Explanation:
To find out what percentage of 500 is 65, you can use the following formula:

percentage = (part/whole) x 100
In this case, the "part" is 65, and the "whole" is 500. So, the formula becomes:
percentage = (65/500) x 100
Simplifying the equation:
percentage = 0.13 x 100 = 13%
Therefore, 65 is 13% of 500.

Question 2

The monthly wage for Jenny is $2,650.00. What would be her new monthly salary if she received a 5% pay raise?

Accepted Answer

Answer

Explanation:
To calculate Jenny's new monthly salary after a 5% pay raise, we can use the following formula:

new salary = current salary + (percent increase x current salary)
First, we need to calculate 5% of Jenny's current salary:
5% of $2,650.00 = 0.05 x $2,650.00 = $132.50
Next, we can substitute the values into the formula:
new salary = $2,650.00 + ($132.50) = $2,782.50
Therefore, Jenny's new monthly salary after a 5% pay raise would be $2,782.50.

Question 3

What percentage of the 148 reams of paper that a department bought are left after 43 of them are used? Round your percentage answer to the nearest whole.

Accepted Answer

71%

Answer

Explanation:
To find the percentage of paper reams left after 43 of them are used, we first need to subtract the number of reams used from the total number of reams bought:

148 - 43 = 105
So there are 105 reams of paper left.
To find the percentage of reams left, we can use the following formula:
percentage = (part/whole) x 100
In this case, the "part" is the number of reams left (105), and the "whole" is the number of reams bought (148). So, the formula becomes:
percentage = (105/148) x 100 = 70.95%
Rounding to the nearest whole number, we get:
percentage = 71%

Therefore, approximately 71% of the reams of paper that the department bought are left after 43 of them are used.

Question 4

What is one-fourth of Jack's weekly income if two-thirds of it is $480?

Accepted Answer

$180

Answer

Explanation:
Let's start by setting up an equation to represent the information given in the problem:

(2/3) * Jack's weekly income = $480
To solve for Jack's weekly income, we can isolate the variable by dividing both sides of the equation by 2/3:
Jack's weekly income = $480 / (2/3) = $480 * (3/2) = $720
Now that we know Jack's weekly income is $720, we can find one-fourth of it by multiplying by 1/4:
One-fourth of Jack's weekly income = $720 * (1/4) = $180
Therefore, one-fourth of Jack's weekly income is $180.

Question 5

A tool room that was 9' x 15' was expanded to 11' x 20'. How much extra floor space was added, in square feet?

Accepted Answer

85 square feet

Answer

Explanation:
The original tool room had an area of:

9 feet x 15 feet = 135 square feet
The expanded tool room has an area of:
11 feet x 20 feet = 220 square feet
To find out how much extra floor space was added, we can subtract the original area from the expanded area:
220 square feet - 135 square feet = 85 square feet

Therefore, 85 square feet of extra floor space was added to the tool room.
