Answer:
Ok, I'm so so so sorry if I get this wrong, but I'ma try.
A.
Juan Increase 25/350 = .071 * 100 = 7 %
Rhia Increase 75/275 = .273 * 100 = 27 %
Max Decrease 40/400 = .1 * 100 = 10 %
B.
Juan sold more than $355 but his increase was less than 10% so he did not get a bonus.
Rhia had an increase of more than 10% but she did not sell more than $355 so she did not get a bonus.
Max had a decrease so he did not get a bonus.
