each. The wholesaler also charges a fee of $160 for each bulk purchase. Kara then sells the video games for $14 each.

Answer: y = 10x + 160

Step-by-step explanation:

The cost follows the linear equation format of:

y = mx + c

Where:

y = dependent variable or the total cost

m is the cost per each additional unit of x

x is the number of video games

c is the constant cost or rather the fee per bulk purchase

Formula is therefore:

y = 10x + 160

Using the formula. Assuming Kara buys 100 video games, the cost would be:

y = 10 * 100 + 160

y = $1,160
