Question

You won a $100 gift card to purchase music and videos through an online store. You bought $48.40 worth of movies and 40 songs.

Write an equation that represents your purchase using s to represent the cost of each song.  
How much did each song cost?

Answer 1

Equation

Total = movies plus songs.

Givens

Total = 100

Movies = 48.4

Songs Cost = x

Number of Songs = 40

Solve

100 = 48.4 + 40x Subtract 48.4 from both sides.

100 - 48.4 = 40x

51.6 = 40x Divide by 40

51.6 / 40 = x

1.29 = x

Conclusion

Each song cost $1.29
