Question

5. Company “A” charges $80 a month for

Answer 1

Answer:

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 = $\frac{5}{100}=\ 0.05\ per\ MB$

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

$\frac{0.05x}{0.05}=\frac{20}{0.05}\\x=400$

Hence,

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