$12b-2$

Step-by-step explanation:

Given expression:

$8b+4b-2$

To write a story that represents the given expression and find the equivalent expression.

Solution:

Selena went to a fruit market with some money in order to buy  apples and  bananas. She finds out that cost of each banana and each apple is $b$ cents. She has 2 cents less than the total amount for which she could buy 8 apples and 4 bananas. Write an expression that represents the total amount Selena had.

If 1 apple cost = $b$ cents

Then 8 apples will cost = $8b$ cents

If 1 banana cost =  $b$ cents

Then 4 bananas will cost = $4b$ cents

Total cost of 8 apple and 4 bananas = $(8b+4b)$ cents

Selena has 2 cents less.

Amount Selena has = $(8b+4b-2)$ cents

The expression can be simplified by adding the like terms.

$8b+4b-2$

⇒ $12b-2$  (Answer)
