Answer:
r = 1/2(s -t/x)
Step-by-step explanation:
Here, we simply want to make r the subject of the formula;
We proceed as follows;
s = 2r + t/x
s - t/x = 2r
Divide both sides by 2
r = 1/2(s - t/x)
498-53=445
445/2=222.5
222.5+53=275.5
so there were 222.5 student tickets sold
to check: 275.5 + 222.5+498
