Give your answer rounded to 2 DP. helppp

Answer 1

Answer:

The final amount if 700 is increased by 4% followed by a further 3% increase is 749.84

Step-by-step explanation:

Step : 1 When 700 is increased by 4 %

So, we get

$\sf \: = \: 700 + 4\% \: of \: 700$

$\sf \: = \: 700 + \dfrac{4}{100} \times 700$

$\sf \: = \: 700 + 4 \times 7$

$\sf \: = \: 700 + 28$

$\sf \: = \: 728$

Step :- 2 When 728 is increased by 3 %

So, we get

$\sf \: = \: 728 + 3\% \: of \: 728$

$\sf \: = \: 728 + \dfrac{3}{100} \times 728$

$\sf \: = \: 728 + \dfrac{2184}{100}$

$\sf \: = \: 728 + 21.84$

$\sf \: = \: 749.84$

Hence, the final amount if 700 is increased by 4% followed by a further 3% increase is 749.84.
