4. Mr. Lakey is a taxi cab driver. He earns [tex]$\$[/tex]5.00[tex]$ per hour plus tips. One week, he works 40 hours and receives $[/tex]\[tex]$287$[/tex] in tips. Find his weekly gross income.



Answer :

To find Mr. Lakey's weekly gross income, let's break it down step by step:

1. Calculate the earnings from his hourly wage:
- Mr. Lakey earns [tex]$5.00 per hour. - He works 40 hours in a week. To find his earnings from the hourly wage alone, we multiply his hourly wage by the number of hours worked: \[ \text{Earnings} = 5.00 \, \text{(dollars/hour)} \times 40 \, \text{(hours)} = 200.00 \, \text{dollars} \] 2. Add the tips received to the hourly earnings: - Besides his hourly earnings, Mr. Lakey received $[/tex]287 in tips.

To find the total gross income for the week, we add the earnings from his hourly wage to the tips he received:
[tex]\[ \text{Gross Income} = \text{Earnings} + \text{Tips} = 200.00 \, \text{dollars} + 287 \, \text{dollars} = 487.00 \, \text{dollars} \][/tex]

Therefore, Mr. Lakey's weekly gross income is [tex]\( 487.00 \)[/tex] dollars.
