I need help with a math problem but it's not letting me sign up. Here Is the problem - Three businesses donated money to charity. The chart shows the pledges made by the businesses. Business B pledged $20 million less than twice the amount pledged by Business A. Business C pledged $200 million less than twice the amount pledged by Business B. If x represents the amount pledged by Business A, write expressions to show the amounts pledged by Business B and Business C in terms of x. (Hint: Do not include the million part in your equations. Ex: 20 million less would be "-20".)
