Question

A restaurant sees about 600 orders on Tuesday. This is down from last Tuesday by about 0.85%. How many did they see last Tuesday

Answer 1

Number of orders seen on last Tuesday = 605

Explanation:

Number of orders seen on Tuesday = 600

It is given that it is 0.85% less than last Tuesday.

Let number of sales on last Tuesday =
`x`

As per question statement:

Number of order on last Tuesday - 0.85% of Number of order on last Tuesday = 600

OR

i.e. if we subtract 0.85% of x from x, it must be equal to 600.

`x-(0.85)/(100)x =600\\\Rightarrow x-(0.85)/(100)x =600\\\Rightarrow (100-0.85)/(100)x =600\\\Rightarrow (99.15)/(100) * x =600\\\Rightarrow x =(600* 100)/(99.15)\\\Rightarrow x =(60000)/(99.15)\\\Rightarrow x \approx 605`

So, there were about 605 order seen last Tuesday.
