the answer this question is  B.

Answer:

b. J + .07 * J

c. (.07 * J) + J

Step-by-step explanation:

The tax on an item is a certain percentage of the cost of the item that is added to the item.

total cost = cost of item + tax on item

In this case, the cost of her items before tax is J.

The tax rate is 7%, so she must add 7% of J to J.

amount of tax: 7% of J = 7% * J = 0.07 * J

Now you add the cost of the items, J, with the amount of the tax, 0.07 * J.

Total cost:

J + 0.07 * J is correct

0.07 * J + J is also correct

Answer:

b. J + .07 * J

c. (.07 * J) + J
