9-45.

There are 5 *x*'s, 2 *y*'s, and 1 *z*.

If there were 7 *x*'s, 1 *y*, and 3 *z*'s the expression would look like this: 7*x* + *y* + 3*z*

If your expression was the one in the example in part (b), you would find the total weight of Jen's fruit with this calculation:

7(5 oz) + 10 oz + 3(48 oz).
