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 =
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.
The variable expression is x(shirt cost) + 8. The answer is x+8.
Yes it could be one........
63/84 divided by 21/21
=3/4
or
63 divided by 84=0.75 which is the same thing as 3/4
