Answer:
The equation to determine the number of T-shirts = 15x+23=473
Step-by-step explanation:
Given:
Donna has a T-shirt printing business.
Charge of grooming one T- shirt = $ 15
Set up fee charged by Donna = $ 23
Total cost received for an order = $ 473
We have to find the number of T-shirts printed by Donna in that order.
Let the number of T-shirt be "x".
Framing the above situation into equation:
⇒ (Unit price of T-Shirt)(Number of T-shirts) + Setup fee = Total charge
⇒ [tex](\$15)(x)+\$23=\$473[/tex]
⇒ [tex]15x+23=473[/tex]
⇒ [tex]15x+23-23=473-23[/tex]
⇒ [tex]15x=473-23[/tex]
⇒ [tex]15x=450[/tex]
⇒ [tex]x=\frac{450}{15}[/tex]
⇒ [tex]x=30[/tex]
The equation is 15x+23=473 and number of T-shirts in that order is 30 piece.
