16/3 is rational simply because it is a fraction made up of whole numbers.

Irrational numbers cannot be expressed as fractions made up of whole numbers.

a salesperson receives a 2.5% commission on sales. what commission does the salesperson receive for $8000 in sales?

Burka [1]

To find the amount we need to multiply
2.5% × 8000

first convert 2.5% to a decimal by dividing by 100 (move decimal 2 places to the left).

2.5% × 80000 =
.025 × 8000 = 200

$200 is the commission

I came in super late

Since we know that 1/4 is equal to 25%, or 0.25 in decimal form, we are able to work with 0.75 in the expression.

We are told to use j as the original price of the jeans, so we can set up the expression:

$j-0.25j$

to represent the cost of the jeans with the discount.

Then to simplify, we simply take out j as a common factor, and solve what's in the parentheses:

$j(1-0.25)$

$j(0.75)$ or $0.75j$

Using this equation, we can solve for the b part of the question. If the pair of jeans originally costs $60, plug in 60 to where j is in the expression:

$0.75j$

$0.75(60)=45$

Therefore, the cost of the jeans after the discount is C) $45.
