Lester · Answer 1

We define the variables:

c: represent the cost per pound of the apples

In addition, we have a 5% tax

The correct expression for the total cost will then be:

5c + 0.05 * 5 * c

This expression can be rewritten in other ways:

5 (c + 0.05c)

5c + 0.05 (5c)

1.05 (5c)

Answer:

The correct answers are:

5 (c + 0.05c)

5c + 0.05 (5c)

1.05 (5c)
