Answer: $52,936
<u>Step-by-step explanation:</u>
Daily tips at 14% of $1400 = $1400(0.14) = $196 per day
$196 per day x 4 days = $784 per week
$784 per week x 52 weeks = $40,768 per year
Regular pay at $9.75 per hour for 6 hours = $9.75(6) = $58.50 per day
$58.50 per day x 4 days = $234 per week
$234 per week x 52 weeks = $12,168 per year
Annual Gross Income = Tips + Regular Pay
= $40,768 + $12,168
= $52,936
Solution: Mark's initial amount 
Mark invest's his inheritance amount in savings account with an annual interest of 3.1%. Therefore, the Mark's interest amount after 1 year is:



Therefore, total amount Mark will have after 1 year
=$30930
Now Charles also has $30000 from his inheritance.
Charles invests his inheritance in a CD paying 5.8% annual.
Therefore, interest amount for Charles after 1 year is:



Therefore, total amount Charles will have after 1 year
=$31740
Therefore, Charles will have $31740 - $30930 = $810 more than Mark
I'd do this by listing the factors of 24, so:
1 & 24
2 & 12
3 & 8
4 & 6
Out of those factors, 2 & 12 add up to 14, so your answer is 2 and 12. I hope this helps!
