Answer:
25 lawns
Explanation:
The rate at which she mows lawns is 5 lawns for every eight hours spent mowing
To fiure out how many lawns she is able to mow at this rate you need to divide the common variables by each other, in this case it is hours
Divide 40 hours by 5 hours
40/8 = 5
Then multiply the amount of "sets" of eight hours by the amount of lawns she mows hourly
5 x 5 = 25
