Answer:I am not sure sorry
Step-by-step explanation:
Hello there! We can solve this question by writing and solving a proportion. Set it up like this:
9/x = 3/100.
This is because 9 is 3% of x number of stores and percents are parts of 100. Setting it up like this will help us get the correct answer. Cross multiply the values . 9 * 100 is 900 and 3 * x = 3x. You get 900 = 3x. Now, divide each side by 3 to isolate the x. 3x/3 cancels out the x. 900/3 is 300. There. x = 300. 9 stores is 3% of 300 stores.
Answer: 11/24
Step-by-step explanation:
whenever u see this — (
it means the opposite of. so the opposite of -5/8 is +5/8.
-1/6 + 5/8 = 11/24
You didn't include the costs of doing repairs at both computer repair firms. I fixed that for you.
ABC Tech ------- $20 service charge plus $15 per hour.
Tech squad ------- $30 service charge plus $10 per hour.
Answer:
Steven's estimate of the repair time is 2 hours.
Step-by-step explanation:
Now in this case, we were told that ABC Tech normally charges $20 service charge and $15 per hour of computer repair service. The second tech firm charges $30 service charge and $10 per hour for computer repair service. We are now simply required to find out or calculate the number of hours of computer repair service whereby the cost of doing repairs at both tech firms become equal.
Let us use "x" to represent that unknown number of hours. The equation needed to calculate this is:
20 + 15x = 30 + 10x
We then pair like terms
15x - 10x = 30 - 20
5x = 10
x = 10/5
x = 2
Therefore the number of hours of computer repair service whereby the cost of doing repairs at both tech firms become equal is 2 hours.
