A college student realized that he was spending too much money on music. For the remaining 5 months of the year his goal is to spend a mean of $60 a month towards music. How much can he spend in December, taking into consideration that in the other 4 months he spent $100, $35, $40, and $55, respectively? Round your answer to two decimal places, if necessary.

70 dollars

Step-by-step explanation:

The average of the other months is 57.5, giving us 2.5 until 60. 2.5 times 4 is equal to 10. 60 plus 10 is equal to 70

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x
