Answer:
The new value after an increase
of £258 by 43 will be: 368.94
Step-by-step explanation:
As we have to increase £258 by 43 using the multiplier method.
Let 'n' represent the new value after the increase of £258 by 43 using the multiplier method.
Using the formula
n = 258 + percentage increase


Factoring out 258

as 1 = 100 / 100 = 100%
so






Therefore, the new value after an increase
of £258 by 43 will be: 368.94
If you had an equation such as 50%x=20, I would convert the percent to a decimal first. So, 0.50x=20. Then I would change the decimal into a simplified fraction. In this case it is 1/2. So, 1/2x=20. Then I would reciprocate the fraction and multiply that by 20. So x=20*2/1. From this, we would get x=40/1, but the 1 is not necessary, so we can write the final answer as x=40.
