Here is how the table would look (Although I cannot see the table, I have done this question before).
Cafeteria Outside Total
Boys 21% 28% 49%
Girls 32% 19% 51%
Total 53% 47% 100%
Step-by-step explanation:
Let x be the money made in sales. Let y be the money made in commissions.
First, convert 2.5% to a decimal.
2.5% = 0.025
Equation:
0.025x = y
Robert:
0.025(8850) = y
y = $221.25
Francisca:
0.025x = 279
x = 279/0.025
x = $11,160
