Answer to Problem 29STP

The cost of each video song is $1.99. option J is correct.

Explanation of Solution

Given information:

2 videos and 7 songs = $10.91

3 videos and 4 songs = $9.93

Let cost of video =x

Cost of songs =y

Hence the equation becomes,

  2x+7y=10.91 . . . (Equation 1)

  3x+4y=$9.93 . . . (Equation 2)

Now multiply first equation with 4 and second with 7 and subtract equation 2 for equation 1 we get,

  4(2x+7y)−7(3x+4y)=4(10.91)−7(9.93)8x+28y−21x−28y=43.64−69.5113x=25.87x=1.99

Hence the cost of each video song is $1.99
