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)
Answer:
25 in
Step-by-step explanation:
The diameter is shown to be 10/4 times the height, so the diameter of the smaller solid is ...
(10/4)×(10 in) = (100/4) in = 25 in
Marcia can write an expression for the number of candles she will have at the end of "h" hours. She can also write an expression for the number of candles Kevin will have at the end of "h" hours. She can set the two expressions equal to each other and solve for "h", the number of hours until each has the same number of candles.
<span>5h = 4h+7 </span>
<span>h = 7 … subtract 4h from each side </span>
<span>In 7 hours, each will have the same number of candles.</span>
