Iwill give brainliest to whoever answers and tells me how to do it in complete ! : d

Strictly speacking, since 'c' is defined in the statement this shoudl work:

Part 1) According to the exercise, the letter 'c' represents the total cost of the three pounds of oranges. So c is the total cost of the three pounds of oranges.

Part 2) Rami has three pounds of oranges. In order to know how much a pound of oranges cost, he will have to divide by 3 the total cost of the three pounds 'c'

Part 3) The cost per pound is:

cost 1 pound of oranges = c/3

To simplify the equation, Erika must isolate the x. This means to get the x by itself. In order to do so, Erika needs to divide 50x by fifty to undo the multiplication. What is done on on side, must be done on the other by the Division Property of Equality. Therefore, Erika must divide seventeen by fifty as well. The answer Erika should end up with is x=0.34
