Based on the information given, the simple interest rate that will be earned will be 13.6%.
- Principal = $5250
- Simple Interest = $6500- $5250 = $1250
- Time = 21 months = 1.75 years.
Simple Interest = PRT / 100
1250 = (5250 × 1.75 × R) / 100
Cross multiply
125000 = 9187.5R
R = 125000 / 9187.5
R = 13.6%

Using proportions and the information given, it is found that:
- The class width is of 14.375.
- The lower class limits are: {19, 33.375, 47.750, 62.125, 76.500, 90.875, 105.250, 119.625}.
- The upper class limits are: {33.375, 47.750, 62.125, 76.500, 90.875, 105.250, 119.625, 134}.
-------------------------
- Minimum value is 19.
- Maximum value is of 134.
- There are 8 classes.
- The classes are all of equal width, thus the width is of:

-------------------------
The intervals will be of:
19 - 33.375
33.375 - 47.750
47.750 - 62.125
62.125 - 76.500
76.500 - 90.875
90.875 - 105.250
105.250 - 119.625
119.625 - 134.
- The lower class limits are: {19, 33.375, 47.750, 62.125, 76.500, 90.875, 105.250, 119.625}.
