Answer:
The difference between their weekly earning is $(1097.25 - 926.25) = $171.
Explanation:
In 7 hours Bri has 13 clients and he earns $14.25 per client.
So, in 35 hours working in a week, Bri will get
clients and he earns $(14.25 × 65) =$926.25 from his clients.
Again, in 5 hours Ali has 11 clients and he earns $14.25 per client.
So, in 35 hours working in a week, Bri will get
clients and he earns $(14.25 × 77) =$1097.25 from his clients.
Therefore, the difference between their weekly earning is $(1097.25 - 926.25) = $171. (Answer)
