Question

apples cost $3.00 per pound, and golden delicious apples cost $2.00 per pound. a childcare center purchases 30 pounds of a combination of the two types apples for a total of $80. apples

	pounds	cost per pound	total
golden delicious	$g$	2

which value could replace $x$ in the table?

• $30 - g + g$
• $3(30 - g)$
• $30 - g(3)$
• $30 - g + 3$

Explanation:

Step1: Recall the formula for total cost

The total cost of an item is calculated by multiplying the number of pounds (quantity) by the cost per pound (unit price). So, Total Cost = Pounds × Cost per Pound.

Step2: Apply the formula to Fuji apples

For Fuji apples, the number of pounds is \( 30 - g \) and the cost per pound is \( 3 \) dollars. So, the total cost \( x \) for Fuji apples should be the product of these two values.
Mathematically, that is \( x = 3\times(30 - g) \), which can be written as \( 3(30 - g) \).

Answer:

\( 3(30 - g) \) (corresponding to the option "3(30 − g)")
