Given that A=xy find the percentage increase in A when both X and Y increase by 10%

Lelechka [254]

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%

(4+5)-2 thxs for answering!!!!!!!!!!!!!!

Arisa [49]

Answer: 7

Step-by-step explanation:

$(4+5)-2$

You can either remove brackets and just do a little addition and subtraction.

$4+5-2$

$9-2\\7$

So the answer is 7.

Or just finish things inside the brackets first.

$(4+5)-2\\9-2\\7$

So the answer is 7.
