2 answers:
Answer: <em>1233.02</em>
Step-by-step explanation:
<em>4% = 0.04</em>
<em>1235 × 0.04 = 49.4 (the original number was increased by this amount)</em>
<em>1235 + 49.4 = 1284.4 (new number after increment)</em>
<em>1 284.4 × 0,04 = 51.376 (the number has been reduced by this amount)</em>
<em>1284.4 - 51.376 = 1233.024- final amount.</em>
<em>Rounded to 2 DP: 1233.02</em>
Answer:
1233.02 to 2 D.P.
Step-by-step explanation:
4 % = 0.04
So to obtain the amount after increase by 4% we multiply by 1.04:
1235 * 1.04 = 1284.4
Decreasing by 4%: we mutriply by 1 - 0.04 = 0.96:
1284.4 * 0.96
= 1233.024.
