To determine which family to work for in order to make more money per hour using the CUBES method, we need to calculate the hourly rate for each family.
CUBES Method:
-
Circle the numbers: Identify the amounts paid and the hours worked.
- Jones family: $75 for 5 hours
- Williams family: $112 for 7 hours
-
Underline the question: Which family should she go to in order to make more money?
-
Bracket the key information:
- Jones family:
- Payment = $75
- Hours = 5
- Williams family:
- Payment = $112
- Hours = 7
- Jones family:
-
Evaluate: Calculate the hourly rate for each family.
-
Jones Family: \[ \text{Hourly rate} = \frac{\text{Total payment}}{\text{Total hours}} = \frac{75}{5} = 15 \text{ dollars per hour} \]
-
Williams Family: \[ \text{Hourly rate} = \frac{\text{Total payment}}{\text{Total hours}} = \frac{112}{7} = 16 \text{ dollars per hour} \]
-
-
Solve the problem: Compare the hourly rates:
- Jones family = 15 dollars per hour
- Williams family = 16 dollars per hour
Since $16 (Williams family) > $15 (Jones family), the family she should go to in order to make more money is the Williams family.
