Question

Your cell phone company charges $0.10 per megabyte of data with a flat fee

of $10. Your friend's company charges $0.25 per megabyte with no flat fee. If
you and your friend paid the same amount for the, same number of megabytes,
How many megabytes did you each use?

Answer 1

Answer: You and your friend used 66.7 megabytes.

Explanation:

Hi, to answer this question we have to write an equation.

Your cell phone company:

y = 10 + 0.10 m

Where:

y: total cost

m = number of megabytes

Your friend's company:

y = 0.25m

If both paid the same, it means that

y = y

And

10 + 0.10m = 0.25m

Solving for m:

10= 0.25m-0.10m

10= 0.15m

10/0.15=m

66.7 =m

You and your friend used 66.7 megabytes.

Answer 2

Problem: If you and your friend paid the same amount for the, same number of megabytes, How many megabytes did you each use?

Given facts: company 1 (mine)
$0.10 per megabyte
$10 flat fee

Company 2 (friend)
$0.25 per megabyte
no flat fee.

method: division
Solution: Company 1 Company 2
$ 0.10 = 1 megabyte $ 0.25 = 1 megabyte
$10/ $0.10 = 100 megabytes $ 10/$0.25= 40 megabytes

(* using $10 as same payment for both)


Answer: Company 1 Company 2
for $10 = 100 megabytes $ 10= 40 megabytes
