Answer:
C. $1,103.88
Step-by-step explanation:
The total cost is:
1785.42 × 1.06635 = 1903.88
There was no physical damage to the pool, only an accidental injury. So Opal pays the $800 deductible, and the insurance pays the rest, which is:
1903.88 − 800 = 1103.88
TL;DR(too long didn't read): answer is 3/4
This question may look confusing, however, it is more easily understood once you see that the fractions appear to be changing more randomly than they are in a way you can recognize, however, they're not. Since they look like that it's because they're being multiplied by a fraction. Split the fractions into two to make it easier. 3/2 and 9/8, just look at them as '3' and '2' and '9' and '8'. 3 becomes 9. Which means either 6 was added or 3 was multiplied by 3. Compare to the next row, 27. 9-->27 can't be 6, so it's being multiplied by 3. Now for the bottom. 2 becomes 8, and knowing that the numerator of the fraction is being multiplied, so is the denominator then, so 2-->8 is 2 times 4. Put the numerator and denominator back together and you have 3/4. The answer is 3/4.
Together it would take a total of 4 hours to completely fill the pool.
1760 divided by 4 equals 440. This is the amount of liters that the second pump will fill the pool in 4 hours, so 440 divided by four is the amount that the second pump will fill the pool in one hour. 440/4= 110.
Now we add 110 to 330 to get the hourly rate of both pumps filling the pool. 110+330=440.
1760/440 equals 4.
So it takes 4 hours for both pumps to fill the pool.
Hope this helps!
