1. Richard bought 4 shirts that cost $85 all together. Each shirt cost the same
amount. The model below represents this situation.




Which equation below and solution for x does the model represent?
A 2x + 2x = 85, x = 42.50

B 4 + x = 85, x = 21.25


C x + x + x + x = 85, x = 21.00

D 4x = 85, x = 21.25
