Question

A family has a phone plan that includes 4 GB of data per month. 10 days into the 30 day month the family has used 1 GB. At that rate how many GB will the family use for the entire month

Answer 1

Answer: The family uses 3 Gb in the entire month.

Step-by-step explanation:

A month has 30 days.

If in 10 days the family uses 1Gb, then in each day the family uses:

R = 1Gb/10 days = 0.1 Gb per day.

Then in 30 days the family uses:

30days*0.1 Gb er day = 3 Gb

The family uses 3 Gb in the entire month.
