Question

An internet provider charges an install fee of $49 and a monthly fee of $99. The total bill was $544. Write an equation to find out how many months

were paid for.

Answer 1

B = $49 + $99m is a good equation; they don't actually ask for the number of months to be found, but I showed it anyway

Explanation:

Let B be the total bill amount.

Let m be the number of months of service provided.

Then the bill total,

B, is $49 for install + $99 times the number of months of service.

B = $49 + $99 x m

*** B = $49 + $99m

Now, we know B is $544, so

544 = 49 + 99m

-49 -49

495 = 99m

495/99 = 99m/99

5 = m

*** After 5 months, the bill is $544
