Answer:
a. $70
b. $(40 + 10x)
Step-by-step explanation:
The standard cost of the charges is $40 per month but an extra $10 per GB over the included amount.
a. Firstly the cost for a month in which he uses 3GB over the limit
we have a standard of $40, then he has to pay $10 per GB for the 3GB over the limit.
Thus the cost of the 3GB is $10 * 3 = $30
The total cost for using 3GB above the limit would be $40 + $30 = $70
b. For using x GB above the limit
He has to pay $10 per each GB above the limit
Thus, the amount to be paid for x GB above the limit would be x * $10 = $10x
So the total amount to be paid would be the base fee plus over the limit fee= $(40 + 10x)
The answer is A. because the side lengths of the shape doesn't change. The side lengths are still 3 and 5.

Lets look at the info we have:-
6 friends
Pay $90 and receive $42 in change.
Question:-
How much does each friend pay?
To answer this first we nee to find out how much they paed in total. lets do that 1st:-
90 - 42 = 48
They paid $48 for the gift.
CHECK OUR WORK:-
48 + 42 = 90
We were RIGHT!!
Now lets divide to find out how much each person paid:-
48 ÷ 6 = 8
Each friend pays $8.
CHECK OUR WORK:-
8 × 6 = 48
We were RIGHT!!
So, each friend pays $8 for the gift.
