Question

r = (cbr + ima) - (cdr + em)
cbr= 18% ima= 1%
cdr= 5% em=12%
what is r?
-1%
23%
2%

Explanation:

Step1: Substitute the values into the formula

We know that \( CBR = 18\% \), \( IMA = 1\% \), \( CDR = 5\% \), and \( EM = 12\% \). Substitute these values into the formula \( r=(CBR + IMA)-(CDR + EM) \).
First, calculate the sum inside the first parentheses: \( CBR + IMA = 18\%+ 1\%=19\% \).
Then, calculate the sum inside the second parentheses: \( CDR + EM = 5\%+ 12\% = 17\% \).

Step2: Calculate the value of r

Now, subtract the two results: \( r=19\% - 17\% = 2\% \)? Wait, no, wait, let's recalculate. Wait, \( 18\%+1\% = 19\% \), \( 5\% + 12\%=17\% \), \( 19\% - 17\% = 2\% \)? But wait, maybe I made a mistake. Wait, no, let's check again. Wait, \( 18 + 1=19 \), \( 5 + 12 = 17 \), \( 19-17 = 2 \). Wait, but the first option is -1%. Wait, maybe I misread the values. Wait, no, the values are CBR=18%, IMA=1%, CDR=5%, EM=12%. Wait, maybe the formula is different? Wait, no, let's do it again. \( (18\% + 1\%)-(5\% + 12\%)=19\% - 17\% = 2\% \). But wait, the options include 2%, so maybe that's correct. Wait, but let's check again. 18 +1 is 19, 5 +12 is 17, 19-17 is 2. So r is 2%? Wait, but maybe I made a mistake. Wait, no, the calculation seems correct.

Wait, wait, maybe the values are different? Wait, the user provided CBR=18%, IMA=1%, CDR=5%, EM=12%. So substituting:

\( r=(18\% + 1\%)-(5\% + 12\%) = 19\% - 17\% = 2\% \). So the answer should be 2%.

Answer:

2%
