At the start of 2014 Tim's house was worth £100000. The value of the house increased by 10% every year Work out the value of his house at the start of 2018

140000

Step-by-step explanation:

use simple interest formula

(p x r x t) divided by 100

substitute:

100000 x 10 x 4 divided by 100 = 10000 x 4 = 40000pounds.

then, add this to the principle = 100000+40000 = 140000

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

the answer is 99.
