r = (cbr + ima) - (cdr + em)\ncbr = 3% ima = 5%\ncdr = 7% em = 3%\nwhat is r?

r = (cbr + ima) - (cdr + em)\ncbr = 3% ima = 5%\ncdr = 7% em = 3%\nwhat is r?

r = (cbr + ima) - (cdr + em)\ncbr = 3% ima = 5%\ncdr = 7% em = 3%\nwhat is r?

Answer

Explanation:

Step1: Calculate the sum in the first parentheses

$(3% + 5%)=8%$

Step2: Calculate the sum in the second parentheses

$(7%+ 3%) = 10%$

Step3: Subtract the second - sum from the first - sum

$r=8% - 10%=- 2%$

Answer:

-2%
