Simple interest means an portion of the principal is added to the principal. In this case the 6% simple interest is will be only from the principal amount which is $800.
A. The finance charge or the interest is $48 ( 6% of $800).
B. The total amount to be repaid is $800 (principal amount) + $48 (6% interest) = $848.
C. To equally pay off the total amount every month, we simply divide $848 by 8 months. $848 / 8 months = $106. The monthly payment would be $106.
The number of scores that are less than 72 is 12.
Solution:
In the given histogram represents the scores of golfers.
x-axis represents the scores and y-axis represents the number of scores.
Number of scores between 66 - 67 = 4
Number of scores between 68 - 69 = 2
Number of scores between 70 - 71 = 6
Number of scores between 72 - 73 = 2
Number of scores between 74 - 75 = 2
To determine the number of scores that are less than 72.
Number of scores less than 72 = 4 + 2 + 6
= 12
Hence the number of scores that are less than 72 is 12.
