Answer: 28
Step-by-step explanation:
Number of cases= 33
Percentage increase= 14.6%
To get the number of cases the previous year, we find the increase from last year and subtract.
= 14.6% of 33
= 14.6/100 × 33
= 4.82
So, the increase was 4.82
To get last year number, we subtract 4.82 from 33.
33 - 4.82 = 28.18 which is approximately 28.
Answer:
29 cases
Step-by-step explanation:
Number of measles cases increased by 14.6% to 33
Question is what was the number of cases prior to the increment.
There are possibly 2 ways to arrive to the answer:
-By multiplying 14% by 33
-By adding 14% to 100% and divide 33 with it.
We try both procedures.
14/100×33=4.62(round it up)
33-4=29(first procedure)
Second procedure is:
100%+14%=114%
Let the number of previous cases be X
114/100×(X)=33
1.14x=33
X=33/1.14
X=28.9(round up to the nearest whole number)
X= 29
