Mike's Music charges $45 per hour. Tim's Tunes charges $80 plus $25 per hour. If you have $240, how many hours will Mike's Music
play?

1. 6 hours
2. 5 hours
3. 6 2/5 hours
4. 5 1/3 hours

Answer 4. (5 1/3 hours)

Step-by-step explanation:

240/45=5.333333333

4. 5 1/3 hours

Step-by-step explanation:

Mike's music:

y = 45x

Tim's Tunes:

y = 80 + 25x

Mike's music:

y = 45x

240 = 45x

x = 240/45

x = 5 1/3

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two
