B.) y = 30x + 55
y should equal the total cost of the service while x is the number of hours it takes.
Answer:
it will be 50000
Step-by-step explanation:
First of all, you would make 6 1/4 into an improper fraction. This makes it 25/4, then you multiply it by 2 to get 50/8 and have common denominators. Divide that by 1/8, which would be 50. Then since each 1/8 costs 2 dollars you would multiply 50 by 2. So, the answer would be that they made 100 dollars.

To round a number, you first have to determine what you are rounding to. in this case, it's the nearest dollar. Then, you determine whether to "round up," to the next higher number, or "round down," which is to stay at the number it's currently at, without the numbers following what you're rounding to. If the number after the place you're rounding to is equal to or higher than 5, you'll round up. If it's lower, you'll round down.
So, for your questions, the answers would look like this:
$8.98 rounds to $9.00, because 9 is bigger than 5.
$6.49 would round down to $6.00, because 4 is less than 5.
$2.51 rounds up to $3.00, because 5 is equal to 5.
$9.78 would round up to $10.00, because 7 is higher than 5.
$39.89 will round up to $40.00, because 8 is bigger than 5.
