It’s 1/5 number a............
Answer:
Step-by-step explanation:
percent increase = (new number - original number) / (original number) * 100
= (1200 - 840) / (840) * 100
= (360) / 840 * 100
= 0.4285 * 100
= 42.85% rounded to nearest percent = 43% <==
keeping in mind that a year has 12 months, thus 6 months is really 6/12 of a year.

If you multiply by 100 you will get the percentage
The answer for c would be 805
