The number of tubs that each of them sold is; 24 tubs each
The number of days it will take for both of them to sell same amount of tubs is; 4 days
Number of cookies that Nicole had already sold = 4 tubs
Number of cookies sold by Josie before counting = 0 cookies
Nicole now sells 5 tubs per day and
Josie now sells 6 tubs per day.
Let the number of days it will take for them to have sold the same amount of cookies be d.
Thus;
5d + 4 = 6d + 0
6d - 5d = 4
d = 4 days
Thus, total number of cookies for both are;
Total for Nicole = 4 + 5(4) = 24 cookies
Total for Josie = 6(4) = 24 cookies
