Abby is going to make rue dyed t shirts for her class to wear on a field trip. Each shirt costs 3.95 and the dye for each shirt costs $0.50. Abby also needs to buy two boxes of salt to add to the mix for $4.50 each. If she has collected $124.70, how many tie dyed t shorts can Abby make?

Since the question states that 2 boxes of salt is needed so
4.50 x 2 = 9

We should minus that off first so that we can find how many shirts she is able to make
124.70 - 9 = 115.7

1 shirt cost : 3.95 + 0.50 = 4.45
She have a total of : 115.70 now

Number of shirts she can make :
115.70 divide by 4.45 which you will get
26

ans : she will be able to make a total of 26 T shirts
