Donna has a T-shirt printing business. She charges $15 per shirt to groom plus a $23 set up fee. Donna charged $473 for one order. Write an equation to determine the number of T-shirts in order

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

⇒

⇒

⇒

⇒

⇒

⇒

⇒

The equation is 15x+23=473 and number of T-shirts in that order is 30 piece.

step-by-step explanation:

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
