Final answer:
Sam earned a total of $1161.50 for mowing lawns in September, October, and November by multiplying the number of lawns by his rate and adding the totals for each month.
Step-by-step explanation:
The student's question is about calculating the total amount of money earned by Sam for mowing lawns over three months. To find the answer, we multiply the number of lawns Sam mowed each month by his rate of $50.50 per lawn, and then add up the totals for each month.
For September (8 lawns): 8 lawns × $50.50 per lawn = $404
For October (6 lawns): 6 lawns × $50.50 per lawn = $303
For November (9 lawns): 9 lawns × $50.50 per lawn = $454.50
Add these amounts together to find the total earnings:
Total earnings = $404 + $303 + $454.50 = $1161.50
Therefore, Sam earned a total of $1161.50 for mowing lawns in September, October, and November.
