at the grocery store, fred paid $15.40 for 3.85 pounds of apples. the unit price fred paid per pound of apples was $4.00

Explanation:

Step1: Recall unit price formula

Unit price is total cost divided by quantity, so formula is $\text{Unit Price} = \frac{\text{Total Cost}}{\text{Quantity}}$.

Step2: Substitute values

Total cost is $\$15.40$, quantity is $3.85$ pounds. So $\text{Unit Price} = \frac{15.40}{3.85}$.

Step3: Perform division

$15.40 \div 3.85 = 4$. So unit price is $\$4.00$ per pound.

Answer:

$\$4.00$
