answer:
the equation
45 + 1.50d = 81
the answer
d = 24

step-by-step explanation:
45 per month is the set bill
1.50 changes per gigabyte
81 is the maximum
45 + 1.50x = 81
-45 -45
1.50x = 36
/1.50 /1.50
x = 24
840060

Answer:

d = 24

Step-by-step explanation:

From the information given in the question, we can make the following equation.

81 = 45 + 1.5d

Now we just solve for "d" and get...

1.5d = 81 - 45

1.5d = 36

d = 36 / 1.5

d = 24
