Answer: 15 hours and 37 minutes
Step-by-step explanation: 6 and 1/2 hours is 6 hours and 30 mins
8 and 2/3 hours is 8 hours and 67 mins
So 8 hours + 6 hours is 14 hours
Since 67 minutes is over an hour, we're going to take 60 minutes from 67, leaving u with 7 minutes
Add the 60 minutes to the 14 hours and you get 15 hours.
Take the 7 minutes and add it to the 30 minutes and you get 37 minutes.
All together the answer is 15 hours and 37 minutes
To answer the question above, I let x be the number of calendars sold. You may use any other letter as this is just for representation. The total income generated in selling calendars is calculated by multiplying the number of calendars with the price. That is,
total income = 5x
If we let total income be y, our equation is further simplified into,
y = 5x
I need to see the answers choices so answer
Let the age of Jay be x years, so age of Jay's father is 2x years .
After 20 years,
Jay's age will be 
And Jay's father age will be 
But at that time, jay's age will be
So we have
Cross multiplication
Therefore Jay's age is 20 years and Jay's Father's age is 40 years .
The amount of interest for $5000 investment that earns 4% per year such that 1$ is $1.040742 a the end of the year will be as follows:
A=P(1+r/100)^n
P=principple
r=rate
n=time
Thus
Amount at the end of the year will be:
A=5000(1+4/100)^1=5200
thus interest earned will be:
5200-5000
=$200
