Final answer:
Frank earned $63.00 by multiplying his rate of $7.00 per lawn with the nine lawns he worked on.
Step-by-step explanation:
To find out how much Frank earned for clearing weeds from his neighbors' lawns, we need to multiply the amount he earns per lawn by the number of lawns he worked on.
Since Frank earns $7.00 per lawn and he pulled weeds from nine lawns, we compute the earnings as follows:
- Multiply the amount earned per lawn by the number of lawns: 7 (dollars per lawn) × 9 (lawns) = 63 (dollars).
Therefore, Frank earned a total of $63.00 for his work.
