5. Company “A” charges $80 a month for their cell phone plan and $5 for a 100MB
of Data. Company “B” charges $60 a
month for their cell phone plan and $10 for
a 100MB of Data. How many mega bytes
of data used would make the cost from
either company equal?

400 megabytes of data used will make the cost from either company equal.

Step-by-step explanation:

Given that:

Per month charges of Company A = $80

Charges of 100 MB = $5 =

Let,

x be the number of MBs consumed.

y be the total charges.

y = 0.05x+80

Per month charges of Company B = $60

Charges of 100 MB = $10 = $0.1 per MB

y = 0.1x+60

For equal charges;

0.05x+80 = 0.1x + 60

80-60 = 0.1x-0.05x

20 = 0.05x

Hence,

400 megabytes of data used will make the cost from either company equal.
