A company loses $7,200 in 8 months. Part A: Write an expression to show the change in profit for each month.

Part B: Find the loss per month.

Part A:

Variable x = change in profit per month

8x = 7200

Part B:

$900 loss per month

Step-by-step explanation:

Part A:

Within 8 months, the company loses $7200. To show a change in profit per month we have to multiply change by 8 months to equal $7200. Since we do not know what the change per month is, we can represent it as a variable. In this case, I will use x.

Variable x = change in profit per month

8x = 7200

Part B:

Solve for the expression we created in part A

8x = 7200

Isolate the variable x by dividing both sides by 8

8x ÷ 8 = 7200 ÷ 8

x = 900

$900 loss per month

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.
