Domain: x values
Range: y values
The relation would need to have (2, y) and (4, y). And also (x, 2) and (x, 8)
See which ones match
Solution: B
3+1/x *x = 7/x*x
3x+1 = 7
3x+1-1=7-1
3x=6
3x/3 =6/3
x =2
Answer: The correct selling price is $29.97.
Step-by-step explanation:
Since we have given that
Cost price of an item = $27
Mark up rate = 11%
So, Amount of mark up would be

Hence, the correct selling price is $29.97.
The manager's likely error is that he has put the selling price the mark up amount only i.e $2.9≈$3 instead of adding the mark up amount to the cost price.
