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

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

b and c
