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.
Answer: 2.31
Step-by-step explanation: 0.462 divided by 0.2 is 2.31. I knew it was going to be over 2 because 0.2 times 2 is 0.4.
Since the exchange rate of euro to USD right now is 1:1.11, therefore he spent 150x1.11=166.5 USD. Therefore, he has 250-166.5=83.5 USD left(assuming the exchange rate is the same, 1.17).

In this problem,, we are told that Mr Nelson needs 5 1/2 yards of fabric to make two dresses. the problem then asks us to find out how much fabric it will take to make only one of the dresses. this means that in order to find out how much fabric is needed to make only one of the two dresses,, we need to divide the total amount of fabric by two. the equation will look like the following:
5 1/2 ÷ 2
the first step to solving this is to convert the mixed number to an improper fraction
11/2 ÷ 2
now,, you can turn the 2 into a fraction and changed the sign because dividing is equivalent to multiplying with the reciprocal value.
11/2 × 1/2
you must then multiply the fractions
11/4
finally,, you need to simplify the fraction to find the answer
2 3/4 yards
since you cannot simplify any further,, the correct answer to your question is A, 2 3/4 yards.
let me know if you have any further questions
