Question

Bo is buying a board game that usually costs B dollars. The game is on sale, and the price has been reduced by 18%.

Which of the following expressions could represent how much no pays for the game?
(options A-E in picture above).

Answer 1

The answer is E.

Explanation:

If the game costs $10 originally then the following would be true:

B = $10

$10.00 x .18 = $1.80 so the discount is $1.80

10.00 - 1.80 = $8.20

Answer 2

A.
`0.82B`

E.
`B-0.18B`

Explanation:

We have been given that Bo is buying a board game that usually costs B dollars. The game is on sale, and the price has been reduced by 18%. We are asked to choose the option that represents amount paid by Bo for the game.

The cost of the game after discount would be original cost minus 18% of original cost. We can write 18 percent as
`(18)/(100)`.

`\text{Cost of game after discount}=B-(18)/(100)\cdot B`

`\text{Cost of game after discount}=B-0.18\cdot B`

`\text{Cost of game after discount}=B-0.18B`

Upon looking at our given choices, we can see that option E is the correct choice.

Let us combine like terms.

`\text{Cost of game after discount}=0.82B`

Therefore, option A and E are correct choices.
