Use the fundamental counting principle and combinations formula to find the total possibilities. use combinations to find the combos then multiply each set of possibilities together.

7 nCr 3 = 35 hamburgers combo possibilities.
5 nCr 2 = 10 sides combo possibilities
8 nCr 3 = 56 drinks combo possibilities
8 nCr 2 = 28 ice cream combo possibilities

Multiply each possibility together to get total possibilities.

Answer:

The number of original students desks were there in school before purchase was made is 980 .

Step-by-step explanation:

Given as :

The total number of new desks purchased including teacher and students = 295

The number of new desks purchased for students = $\frac{1}{4}$ of original students desks available

The number of new desks purchased for teachers = 50

Let The number of original students desks available before purchase = S

Now, According to question

∵ The total number of new desks purchased including teacher and students = 295

I.e The number of new desks purchased for students + The number of new desks purchased for teachers = 295

Or, $\frac{1}{4}$ of S + 50 = 295

Or, $\frac{1}{4}$ × S = 295 - 50

Or , $\frac{1}{4}$ × S = 245

∴ S = 245 × 4 = 980

So, original desks available for students = S = 980

Hence The number of original students desks were there in school before purchase was made is 980 . Answer
