Question

The robotics club is selling shirts for a fundraiser. They have purchased a box of shirts for $400 at $5 per shirt. To promote their fundraiser, they have also spent $60 on advertising.

Answer 1

80x-460=300

80x=760

Explanation:

In order to know which equation is best, you have to add the total expenses the robotics club had.

Expenses:

1. box of shirts = $400
2. advertising = $60

Let's add: $400 + $60 = $460

Next, you have to know how many of the shirts were purchased.

• $400 ÷ $5 = 80

Now, let's compute.

• 80x - 460 = 300
• 80x = 300 + 460
• 80x = 760
• x = $9.5

or

• 80x=760
• x = 760 ÷ 80
• x = $9.5

This means that the robotics club has to sell the shirts at $9.5 each in order to have a $300 profit.
