Question

Write an expression to show how much Gretchen paid for drama,action, and comedy videos if she paid $4 for each at a sale. Evaluate the expression

Answer 1

Step-by-step explanation

To determine how much Gretchen paid, we will have to list out the number of Video purchases made for drama, action, and comedy videos.

Let the Action videos be represented by A

Let the Comedy videos be represented by C

Let the Drama videos be represented by D

Also,

A has 3 purchases

C has 5 purchases

D has 2 purchases

Therefore, we will have the expression

`3A+5C+2D`

If she paid $4 for each, then

The total videos purchased = 3+5+2=10

Thus, the total amount paid will be

`\begin{gathered} 10p \\ \text{where p is the price she paid for each video} \\ \text{Thus, } \\ \text{she paid} \\ 10(4)=\text{ \$40} \end{gathered}`

Thus, Gretchen paid $40
