A house was built in 1985 and cost $62000. It was sold in 2003 for $310000.
(a) Work out the 1985 price as a percentage of the 2003 price.
(b)Calculate the percentage increase in the price from 1985 to 2003.

a) 20%

b) 400%

Step-by-step explanation:

In a) you firts do

$310000=100% what about $62000.Then cross multiply

$62000×100%=6200000÷310000=20%

In b) you first do

$62000=100% what about $248000.Then cross multiply

$248000×100=$24800000÷62000=400%

answer: 1000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
