As a pizza deliverer, Sarah is paid [tex]$6.25 per hour and $[/tex]0.32 per mile. If [tex]$t$[/tex] represents the number of hours Sarah works in a week and [tex]$m$[/tex] represents the number of miles driven for deliveries that week, which of the following equations represents [tex]$P$[/tex], Sarah's income for the week (not including tips)?

A. [tex]P = 6.25t + 0.32m[/tex]

B. [tex]P = 0.32t + 6.25m[/tex]

C. [tex]P = 32t + 6.25m[/tex]

D. [tex]P = 6.25t + 32m[/tex]



Answer :

Certainly! Let's break down the problem step-by-step to determine the correct equation to represent Sarah's income for the week.

1. Identify Sarah's Pay Rates:
- Sarah gets paid \[tex]$6.25 for each hour she works. - Sarah gets paid \$[/tex]0.32 for each mile she drives for deliveries.

2. Define Variables:
- Let [tex]\( t \)[/tex] represent the number of hours Sarah works in a week.
- Let [tex]\( m \)[/tex] represent the number of miles Sarah drives for deliveries in a week.

3. Calculate Income Based on Hours Worked:
- If Sarah works for [tex]\( t \)[/tex] hours, her income from working these hours is:
[tex]\[ \text{Income from hours} = 6.25 \times t \][/tex]

4. Calculate Income Based on Miles Driven:
- If Sarah drives [tex]\( m \)[/tex] miles for deliveries, her income from driving these miles is:
[tex]\[ \text{Income from miles} = 0.32 \times m \][/tex]

5. Combine Both Sources of Income:
- Sarah’s total weekly income [tex]\( P \)[/tex] is the sum of her income from hours worked and miles driven:
[tex]\[ P = (\text{Income from hours}) + (\text{Income from miles}) \][/tex]

6. Form the Equation:
- Substitute the expressions for each part of the income into the equation:
[tex]\[ P = 6.25t + 0.32m \][/tex]

Therefore, the equation that represents Sarah's income [tex]\( P \)[/tex] for the week, taking into account both her hourly rate and the miles driven, is:

[tex]\[ \boxed{P = 6.25t + 0.32m} \][/tex]

This corresponds to the option:

A. [tex]\( P = 6.25t + 0.32m \)[/tex]
