Y=x^-3...................
A=xy
If there is 10% increase in x then,
New value of x = x + 10%of x =1.1x
similarly for y
New value of y after increase= 1.1 y
New value of A after increase in x and y = 1 .1x × 1.1 y= 1.21xy
now
increase amount in A= New value of A - old value of A
=1.21xy - xy= 0.21xy
percentage increase in A= (0.21xy÷xy )× 100= 21%

Answer:pls is it all we are to ans
Step-by-step explanation:
E=9h+1.5(9)(h-40)
e=9h+13.5(h-40), since h=49
e=9(40)+13.5(9)
e=9(40+13.5)
e=9(53.5)
e=$481.50
