Let $x$ represent the weight (in ounces) of one banana, $y$ represent the weight (in ounces) of one peach, and $z$ represent the weight (in ounces) of one melon. Jen placed bananas, peaches, and melons in her shopping basket while at the grocery store. The diagram below represents her selection of fruit.

1. According to the diagram, how many of each fruit did Jen place in her basket?

   Hint (a):

   There are $5 \: x'\text{s}$, $2\: y'\text{s}$, and $1 \:z$.

2. Use the diagram to write a variable expression that represents the weight of the fruit she selected.

   Hint (b):

   If there were $7\: x'\text{s}$, $1 \: y$, and $3 z'\text{s}$ the expression would look like this: $7x + y + 3z$

3. If each banana weighs $5$ ounces, each peach weighs $10$ ounces, and each melon weighs $48$ ounces, use the expression you created in part (b) to find the total weight of Jen's fruit.

   Hint (c):

   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:
   $7\left(5 \text { oz}\right) + 10 \text{ oz } + 3\left(48 \text{ oz}\right)$.
