Given the range of the load done in two coin-laundry stores
The first store has:
between 72 and 116 loads have done on Thursday
between 113 and 172 loads have done on Friday
The second store has:
between 143 and 231 loads have done on Thursday
Between 192 and 279 loads were done on Friday
Let (k) represents loads of laundry, we will find the possible range for (k)
So, the smallest possible value of k = 72 + 113 + 143 + 192 = 520
And the highest possible value of k = 116 + 172+231+279 = 798
so, the answer will be:
[tex]520\le k\le798[/tex]
