On a Monday, Kerry groomed 15 cars in 10 hours and Watson groomed 10 cars in 8 hours they each earn$12.75 for each cat groomed. Assuming that

$446.25

Step-by-step explanation:

Since both groomers are paid by the amount of cats they groom, time in the context of this problem is completely negligible. So, we can simply multiply the cats they groom per day by the amount of days in the week (7) and multiply that by the amount they get paid per cat.

Kerry:

Kerry grooms 15 cats in a day. Thus, every week he will groom 15 x 7 = 105 cats. He gets paid $12.75 per cat, so every week he will earn:

Watson:

Watson grooms 10 cats in a day, so every week he will groom 10 x 7 = 70 cats. He also gets paid $12.75 per cat, so every week he will earn:

So the difference in between the two will be:

Therefore, the difference in Kerry and Watson's earning, weekly, is $446.25.
