Question

Use the multiplier method to increase £258 by 43

Answer 1

The new value after an increase

of £258 by 43 will be: 368.94

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

`=258+\left(43\%\:258\right)`

`=258\:+\:43\%\:* 258`

Factoring out 258

`=\left(1\:+\:43\%\right)\:* \:258`

as 1 = 100 / 100 = 100%

so

`=\left(100\%\:+\:43\%\right)\:* \:258`

`=143\%\:* \:258`

`=(143)/(100)* 258`

`=\:(143* 258\:\:)/(100)`

`=\:(36,894\:\:)/(100)`

`=368.94`

Therefore, the new value after an increase

of £258 by 43 will be: 368.94
