Answer:
Theodore's
the interest rate in Theodore's bank is higher
Step-by-step explanation:
A rational investor would want to invest in a bank that offers a higher interest rate because more money is usually preferred to less money.
If the same amount, 1500 was deposited in both banks,
interest in Theodore's bank after 4 years = 1500 x 0.042 x 4 = $252
$252 would be preferred to the $216 earned at Bella's bank
Answer:the present age of the father is 45 years
Step-by-step explanation:
Let x represent the present age of the father.
Let y represent the present age of the son.
Let z represent the age of the daughter.
A father is 3 times as old as his son. This means that
x = 3y
his daughter is 3 years younger than the son. It means that
z = y - 3
The sum of their ages 3 years ago was 63. This means that
x - 3 + y - 3 + z - 3 = 63
x + y + z - 9 = 63 - - - - - - - - - - 1
Substituting x = 3y and z = y - 3 into equation 1, it becomes
3y + y + y - 3 - 9 = 63
5y - 12 = 63
5y = 63 + 12 = 75
y = 75/5 = 15
x = 3y = 3 × 15
x = 45
z = y - 3 = 15 - 3
z = 12
Answer:
4.8 hours
Step-by-step explanation:
First, divide the distance by time to get velocity.
S = D/T
S = 360/4
S = 90 mph
Then, subtract 15 from 90 to get the new speed.
90 - 15 = 75
Lastly divide the distance by the new speed to get time.
T = D/S
T = 360/75
T = 4.8
Therefore, it would take the car 4.8 hours to travel 360 miles at 75 miles per hour.
