r = (cbr + ima) - (cdr + em)\ncbr = 20% ima = 10%\ncdr = 10% em = 30%\nwhat is r?\n-10%\n-4%\n-7%

Answer

Explanation:

Step1: Substitute values into formula

Substitute ( CBR = 20% ), ( IMA = 10% ), ( CDR = 10% ), ( EM = 30% ) into ( r=(CBR + IMA)-(CDR + EM) ). We get ( r=(20% + 10%)-(10% + 30%) ).

Step2: Calculate inside parentheses

First, calculate ( 20%+10% = 30% ) and ( 10% + 30% = 40% ).

Step3: Subtract the two results

Then, ( r = 30% - 40%=-10% ).

Answer:

-10%
