The variable, c, represents ✔ the cost of one songthe cost of all songsthe number of songsthe type of song

The cost of each song is part of a total, so the operation is additiondivision✔ multiplicationsubatraction

The correct equation to solve this problem is c + 6 = 7.80c - 6 = 7.80✔ 6c = 7.80

The solution of the equation is g = 2.7g = 10g = 22✔ g = 96.

Check the solution by substituting 2.71022✔ 96 in for g and simplifying.
