Question

which answer choice shows an inequality that represents the problem below? brittanys mom gave her $15.00 to buy school supplies. brittany needs to buy 3 notebooks and some mechanical pencils. if each notebook costs $2.99 and each mechanical pencil costs $1.50, how many mechanical pencils can brittany buy using only the money her mom gave her? 1.5x + 3 ≤ 15, 3x + 1.5 ≤ 15, 2.99x + 1.5 ≤ 15, (3 × 2.99) + 1.5x ≤

Explanation:

Step1: Calculate the cost of notebooks

The cost of 3 notebooks is \(3\times2.99\).

Step2: Calculate the cost of mechanical pencils

Let \(x\) be the number of mechanical pencils. The cost of mechanical pencils is \(1.5x\).

Step3: Set up the inequality

The total cost of notebooks and mechanical pencils should be less than or equal to \(15\). So the inequality is \((3\times2.99)+1.5x\leq15\).

Answer:

\((3\times2.99)+1.5x\leq15\)
