Question

a lotion is made from an oil blend costing $1.50 per ounce and glycerin costing $1.00 per ounce. four ounces of lotion costs $5.50. which value could replace x on the table?

lotion	ounces	cost per ounce	total
glycerin	g	1.00
mixture	4		5.50

options:
(4 - g)g
(4 - g) + 1.5
4g - g(1.5)
(4 - g)1.5

Explanation:

Step1: Recall Total Cost Formula

Total cost for a component is ounces multiplied by cost per ounce.

Step2: Apply Formula to Oil Blend

For oil blend, ounces are \(4 - g\) and cost per ounce is \(1.50\). So total cost \(x=(4 - g)\times1.5\) or \((4 - g)1.5\).

Answer:

\((4 - g)1.5\)
