Question

Keisha is a software salesman. His base salary is $2400, and he makes an $40 for every copy of history is fun she sells. Her total pay, P (in dollars), after selling c copies is given by the following.

P=40c+24000

anwser the following questions.

(a) what is keisha's total pay if she sells 22 copies?

$

(b) if keisha's total pay is $3680, how many copies did she sell?

copies

Answer 1

(a) Bet, let's do the math. If Keisha sells 22 copies of "History is Fun", we plug that into the equation, right?

So we got P = 40c + 2400. We're swapping out the c for 22, because that's how many copies she moved. That makes the equation P = 40 * 22 + 2400.

Doing the math, it's like 880 + 2400, which equals to 3280.

So, if Keisha sells 22 copies, she's getting a bag of $3280.

(b) Alright, so now we got a total pay of $3680, and we're gonna figure out how many copies Keisha sold.

Here's the equation again: P = 40c + 2400. This time, we know P is $3680, so we swap that in to get 3680 = 40c + 2400.

We gotta isolate c, so we subtract 2400 from both sides: 3680 - 2400 = 40c. That leaves us with 1280 = 40c.

To find out c, we divide both sides by 40: 1280 / 40 = c. Doing the math, we get c = 32.

So, if Keisha's total pay is $3680, she sold 32 copies of "History is Fun". That's some serious hustle!

Answer 2

a) 3280, b) 32 copies

Explanation:

Given: 40x + 2400

Where 40x represents the dollars she earns for every copy, and 2400 for base salary.

a) Given that she earns an extra 40$ for every copy, multiply the number by 22 copies and add the base salary to obtain her total pay.

40(22) + 2400 = 3,280 dollars she will earn.

a) Given that she earns a base salary of 2400, subtract her pay from the salary and you will the difference of how much she earned from copies.

3680 - 2400 = 1280 dollars earned.

Given that she earns an extra 40$ for every copy, divide the amount that she earned from copies by 40.

1280/40 = 32 copies sold.

Keisha sold 32 copies in question B.
