Question

samir and jillian share a phone plan. each month they can use a combined total of up to 8 gb of data. so far this month, samir has used 4.23 gb and jillian has used 2.89 gb. they want to know whether they still have data left to use. you found that samir and jillian have used about 7 gb of data. do samir and jillian have any data left to use? samir and jillian have used less than 8 gb of data, so they do have data left to use.

Explanation:

Step1: Calculate total used data

$4.23 + 2.89 = 7.12$ GB

Step2: Compare to plan limit

$7.12 < 8$ GB

Answer:

Yes, Samir and Jillian have data left to use. They have used 7.12 GB total, which is less than their 8 GB monthly limit, so they have $8 - 7.12 = 0.88$ GB of data remaining.
