Tina's tops is a new store that prints personalized t-shirts. she charges a $12 one-time fee for the design. solve the equation 72=12+4x and explain what the solution tells you about the number of shirts printed and the cost.

Solve:

1) 72=12+4x

2) 72-12=4x

3)60=4x

4)60/4=x

5)15=x

This COULD be telling us that 15 t shirts and the $12 dollar design for all of them costs a total of $72.

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
