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;
[tex]\frac{1}{4}\ of\ x=245\\\frac{1}{4}x=245[/tex]
Multiplying both sides by 4;
[tex]4*\frac{1}{4}x=245*4\\x=980[/tex]
There were 980 student desks originally.
