Answer:
3.93 per hour
Step-by-step explanation:
The first 4 hours is at 20 hours / 4 hours or 5 dollars an hours
The second line has a slope of 2.50 dollars an hour
But there is also a surcharge when you go over 4 hours
That is a 5 dollar flat rate at 4 hours
Assuming that we do not include the flat rate in the hourly calculation
4 hours * 5 dollar + 3 hours * 2.50 = 20+7.50
27.50 is the hourly charge
Divide by 7 hours
3.928571429
3.93 per hour
I think it is 26 sorry if I’m wrong
Answer:
The finance charge for this month is $162.06
Step-by-step explanation:
Hi
First of all, as we have the interest rate of a year , but we need the monthly rate of interest, so .
Then we can compute how much is the finance charge for this month, hence
To solve this problem, you'll want to substitute the variables for the values you are given and follow the order of operations. Let's substitute first, shall we?
xz becomes 4 times 1.
4y becomes 4 times 2.
2z becomes 2 times 1.
Now that we have everything substituted in, we have our new equation.
4*1(4*2 - 2*1) With the asterisks representing the multiplication sign.
Now, solving those first easy problems as the first step, we get..
4(8-2)
Remember to follow order of operations! Do the problem in the parentheses first, 8-2.
Now we have 4(6).
Assuming the problem is exactly how you wrote it and you are supposed to multiply the two numbers, your answer is 24.
