Question 1171348
investment in stock A = 6100
investment in stock B = 6480
investment A stock went down 2% meaning it is now worth .98 * what it was worth last year.
investment B stock went down 10% meaning it is now worth .90 * what it was worth last year.
investment in stock A and B are now worth...
6100 * .98 = 5978
6480 * .90 = 5832
the total investment in both stock A and B is now worth...
5978 + 5832 = 11810
the total investment in both stock A and B last year was worth...
6100 + 6480 = 12580
divide this year's total by last year's total to get:
11810 / 12580 = .9387917329
multiply by  100 to get 93.87917329%
round to 1 decimal place to get 93.9%.
the overall investment is worth 93.9% of what it was last year.
that's a drop of 100% - 93.9% = 6.1%.
that should be your answer.
