1. at the deli, one pound of turkey costs $7.98. mr. epstein buys 3 pounds of turkey. how much will the turkey cost?

Explanation:

Step1: Identify the formula

To find the total cost, we use the formula: Total Cost = Cost per unit × Number of units. Here, the cost per pound (unit) is $7.98, and the number of pounds (units) is 3.

Step2: Perform the multiplication

Calculate \( 7.98\times3 \).
\( 7\times3 = 21 \), \( 0.98\times3 = 2.94 \), then add them together: \( 21 + 2.94 = 23.94 \).

Answer:

The turkey will cost $23.94.
