Step-by-step explanation:

1)

$819

2)

Month 4

Step-by-step explanation:

1)

The average is the sum of the values, divided by the number of values.

We want the average to be $1000, ie we want  Fridays total (1073) + Saturdays total (1108)  + sundays total (x) , all divided by three to equal 1000.

(1073 + 1108 + x )/3= 1000

2181 + x = 3000

∴ x = $819

2)

The amount you pay can be represented by the function '20+25x', where x is the amount of months.

Let this equal 120 for your answer.

20+25x=120

25x=100

x=4
