Question

Sal earns $760 per week. Lidia earns $475 per week. Are their salaries proportional if Sal works 40 hours per week and Lidia works 25 hours per week?

Answer 1

Sal and Lidia's salaries are proportional because they both earn $19 per hour when their weekly salaries are divided by the number of hours they work.

Step-by-step explanation:

To determine if Sal's and Lidia's salaries are proportional based on their hours of work, we need to calculate their respective hourly rates. For Sal, we calculate the hourly rate by dividing his weekly salary of $760 by 40 hours per week. For Lidia, her hourly rate is calculated by dividing her weekly salary of $475 by 25 hours per week.

Let's calculate:

• Sal's hourly rate: $760 ÷ 40 hours = $19 per hour
• Lidia's hourly rate: $475 ÷ 25 hours = $19 per hour

Since both Sal and Lidia earn $19 per hour, we can conclude that their salaries are indeed proportional with respect to the number of hours they work.
