What is the final amount if 1634 is decreased by 3% followed by a 4% increase? Give your answer rounded to 2 DP.

1648.38

Step-by-step explanation:

Amount after 3% decrease

= 1634 x 0.97 = 1584.98

Amount after 4% increase

= 1584.98 x 1.04 = 1648.38

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
