There were 980 student desks originally.

Step-by-step explanation:

Number of desks purchased = 295

Desks bought for teacher = 50

Desks for students = No. of desks purchased - desks bought for teachers

Desks for students = 295 - 50 = 245

This is 1/4 of number of original student desks.

Let x be the number of original student desks.

According to statement;

$\frac{1}{4}\ of\ x=245\\\frac{1}{4}x=245$

Multiplying both sides by 4;

$4*\frac{1}{4}x=245*4\\x=980$

There were 980 student desks originally.
