Choose the correct expression and solution to this problem. O A. The expression is 2(15 + 6). Greta will spend $42. OB. The expression is 2(15 - 6). Greta will spend $18. C. The expression is 15(6 - 2). PREVIOUS

Answer 1

The teammates are 15 but 6 of them do not want the photo, so the number of the teammates who wants the photo is 15 - 6.

Now, each photo cost $2 adn the number of photo is equal to the number of teammates who wants the photo which is (15-6), so the expression for the total cost is:

`2\cdot(15-6)_{}`

We have to multiply the cost of each photo for the number of photo Greta will buy.
