Question

Which answer choice shows an inequality that represents the

problem below?
Audrie's mom gave her $20.00 to buy school supplies. Audrie
needs to buy 4 packs of index cards and some notebooks. If
each pack of index cards costs $1.95 and each notebook costs
$1.99, how many notebooks can Audrie buy using only the
money her mom gave her?

Answer 1

Audrie can buy 6 notebooks using the money her mom gave her.

Step-by-step explanation:

To find out how many notebooks Audrie can buy using the money her mom gave her, we need to determine the cost of the index cards and subtract it from the total amount of money. Each pack of index cards costs $1.95. Since Audrie needs to buy 4 packs of index cards, the total cost of the index cards is 4 x $1.95 = $7.80. Subtracting this from the $20.00 Audrie has, she is left with $20.00 - $7.80 = $12.20. The cost of each notebook is $1.99. Therefore, Audrie can buy $12.20 / $1.99 = 6 notebooks using only the money her mom gave her.
