Answer:
4 years
Step-by-step explanation:
The simple interest = $6,500 - $5,000 = $1500
From the formula for simple interest;
I=PRT/100
T= 100 I/PR
T= 100 × 1500/5000 × 7.5
T= 150000/37500
T= 4 years
Second option:

The riddle answer is 24.
A riddle for the number 68 is: 12 more than 14 times 4
Answer:
Lowest score needed=4.92
Step-by-step explanation:
Using the standard normal distribution table we find the value of standard normal deviate corresponding to area of 15%
For area of 15% we have Z= -1.04
Thus we have

Applying values we get

Thus lowest score needed = 4.92
