Answer:
Cat sleeps 420 hours than Alice in a month
Step-by-step explanation:
Given:
Number of hours Alice sleeps per night = 9 hours
Number of hours Cat sleeps per night = 20 hours
To Find:
How many more hours does a cat sleep in 1 month that Alice
Solution:
Let
The total number of hours for which Alice Sleeps in one month be x
The total number of hours for which Cat sleeps in one month be y
Step 1: Number of hours for which Alice Sleeps in one month
X = number of days in a month X Number of hours Alice sleeps per night
X = 30 X 9
X = 180 Hours
Step 2: Number of hours for which Cat Sleeps in one month
y= number of days in a month X Number of hours cat sleeps per night
y = 30 X 20
y = 600 Hours
Now ,
=> y – x
=>600 – 180
=>420 hours
Chris will have $7810 at the end of 12 years in his account if the simple interest rate is 3.5%.
According to the question,
We have the following information:
Chris invested $5,500. The investment had a simple interest rate of 3.5%. And he plans to leave the investment alone for 12 years.
Now, we know that the following formula is used to find the simple interest on an investment:
Interest = principal*rate*time/100
Principal = $5500
Rate = 3.5
Time = 12 years
Interest = (5500*3.5*12)/100
Interest = $2310
Now, the total amount in his account will be:
5500+2310
$7810
Hence, Chris will have $7810 at the end of 12 years in his account if the simple interest rate is 3.5%.
