Question

Suppose that in 2012, ABC Industries earned a profit of $1400. You know that in 2012 profits grew by 40% from their 2011 level. Also in 2011, profits grew by 25% from their 2010 level. What is The sum of the profits of 2010 and 2011?​

Answer 1

Answer:

$1,800

Step-by-step explanation

Profit in 2012 = 1400 which is 40% from 2011

Profit in 2011 = 'x' which is 25% from 2010

Profit in 2010 = 'y'

2010 + 2011 = x + y = ?

Solving for x

1400=x(0.40)+1

1400=x(1.40)

1400/1.40=x

1000=x

Solving for y

1000=y(0.25)+1

1000/1.25=y

800=y

x+y = 2010 + 2011 = 1000 + 800 = 1800
