A family pays $21.99 each month for its long distance phone service. This is 80% of the original price of the phone service. What is the original price of the phone service? Round to the nearest cent if necessary.

The original price of the phone service is $27.49.

Step-by-step explanation:

With the information provided, you can use a rule of three to find the original price that would represent 100% given that $21.99 represents 80% of that price:

21.99 → 80%

   x    ← 100%

x=(21.99*100)/80

x=27.49

According to this, the answer is that the original price of the phone service is $27.49.
