A verity pack of juice includes five bottles of grape juice and several bottles of apple juice use G to represent the cost of ea
Damm [24]

Answer:

15G+21a

Step-by-step explanation:

Let G represent cost of each bottle of grape juice and a represent the cost of each bottle of apple juice.

We have been given that a verity pack of juice includes 5 bottles of grape juice and 7 bottles of apple juice.

The cost of 5 bottles of grape juice would be 5G and cost of 7 bottles of apple juice would be 7a.

Since one verity pack includes 5 bottles of grape juice and 7 bottles of apple juice, so cost of one variety pack would be 5G+7a.

The expression for total cost of three verity packs would be three times cost of one verity pack that is 3(5G+7a)

Let us simplify our expression as:

3*5G+3*7a\Rightarrow 15G+21a

Therefore, our required expression would be 15G+21a.
