Answer: Maya made $630 more than Sam.
Explanation:
The total amount that Sam, Aria and Maya got paid for painting the house is $2160.
Since they worked for different number of hours on the job, the money was split in the ratio of
4 : 9 : 11
The total ratio is the sum of the proportions. It becomes
4 + 9 + 11 = 24
Therefore, the amount that Sam made was
4/24 × 2160 = $360
The amount that Aria made was
9/24 × 2160 = $810
The amount that Maya made was
11/24 × 2160 = $990
The difference in the amounts made by Maya and Sam is
990 - 360 = $630
