Question

A school choir needs to make T-shirts for its 75 members and has set aside some money in their budget to pay for them. The members of the choir decided to order from a printing company that charged $3 per shirt, plus a $50 flat fee for shipping. If the school spends $113 total, how many T-shirts did they buy?

Answer 1

Note that:

• Equation created: 50 + 3(Shirts) = $113

Solve the equation to find out how many shirts did the school choir bought.

• => 50 + 3x = $113
• => 3x = 113 - 50
• => 3x = 63
• => x = 21

The school choir bought 21 shirts.

Answer 2

21

Explanation:

Let x = number of t-shirts

Let y = total cost

If the company charges $3 per shirt, plus a $50 flat fee for shipping:

⇒ y = 50 + 3x

If the school spends $113 total, subtitute y = 113 and solve for x:

⇒ 113 = 50 + 3x

⇒ 113 - 50 = 3x

⇒ 63 = 3x

⇒ x = 63 ÷ 3

⇒ x = 21

Therefore, the choir bought 21 t-shirts
