Answer:
$127.50
Step-by-step explanation:
To answer this you will need to figure out how many days each person is working each week based on their number of hours and how many hours they work. Use this to determine the number of dogs groomed and then multiply by the hourly rate.
Dana works 4 days (40/10) and Monique works 5 days (40/8).
Dana: 15 dogs per day x 4 days a week x $12.75 per dog = $765 a week.
Monique: 10 dogs per day x 5 days a week x $12.75 per dog = $637.50 a week.
765 - 637.50 = $127.50.
The difference is $127.50.

Answer:
Darlene bought more fabric
Darlene bought 3.4 yards more
Step-by-step explanation:
Darlene = 7 yards + 20% extra
= 7 yards + (20% of 7 yards)
= 7 + (20% × 7)
= 7 + (0.2 × 7)
= 7 + 1.4
= 8.4 yards
Chris = 4 yards + 25% of 4 yards
= 4 yards + (25% of 4 yards)
= 4 + (25% × 4)
= 4 + (0.25 × 4)
= 4 + 1
= 5 yards
Darlene bought more fabric
How much more?
Darlene - Chris
= 8.4 yards - 5 yards
= 3.4 yards
Darlene bought 3.4 yards more
