Question

The cost to produce a custom designed t-shirt is five dollars per shirt plus a 40 dollar design fee. What would be the cost to produce 50 shirts?

Answer 1

you always have to pay 40 dollar design. then every shirt costs 5 dollar. so for 50 shirts you must pay
50*5$+40$=250$+40$=290$

Answer 2

Equation for shirts (x represents t shirts):
5x+40
50 tshirts sub into x
=50*5x+40
=290 dollars

Answer 3

why 50*5x[sic]+40 ? i think you subbed the x? ;)
