Domain={8,9}
Range = { -3,-4,-6,-9}
No relation is not function as elements in domain are related to more than one element of codomain
Imagine the graph of f(x)=|x|. This can only output positive values (

).
Then f(x)=|x|+2 is the same graph shifted upwards by two units meaning it can only output values bigger or equal to than 2. So the range is
Interesting problem.
First - let's figure cost of each uniform at purchase.
3,000/40 = $75 each
When some uniforms were returned at $40 - there was a difference of $35 in what they paid and what they rec'd in return. ($75 - 35 = $40)

B and C make sense to me.
