Question

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

Explanation:

Step1: Substitute values into formula

Substitute \( CBR = 18\% \), \( IMA = 1\% \), \( CDR = 5\% \), \( EM = 12\% \) into \( r=(CBR + IMA)-(CDR + EM) \).
\( r=(18\% + 1\%)-(5\% + 12\%) \)

Step2: Calculate inside parentheses

First, calculate \( 18\%+1\% = 19\% \) and \( 5\% + 12\%=17\% \).
\( r = 19\% - 17\% \)

Step3: Subtract the two percentages

Subtract \( 17\% \) from \( 19\% \).
\( r = 2\% \)

Answer:

\( 2\% \)
