What is the relation between work and time?
The total time taken is inversely proportional to the rate of work. If a unit of work is done in total n number of days, then the total work done in a day is,
[tex]W=\dfrac{1}{n}[/tex]
Melissa earns $68 a day mowing lawns. The total amount she earns is $748.
To find the number of days she must work to earn $748, we have to divide the one-day earning to the total amount earned by her. Thus, the number of days she worked is,
[tex]n=\dfrac{748}{68}\\n=11[/tex]
Hence, the number of days must Melissa work to make $748, when she earns $68 a day mowing lawns is 11.
