Question

If I know that 40% of a number is 100 and I multiply that number by 2, what's 40% of that new number?

Answer 1

Answer: 200

Explanation:

40% of y = 100

40/100 of y = 100

40y/100 = 100

40y = 100 multiplied by 100

40y/40 = 10000

y = 250.

40% of 2 multiplied by 250

40/100 of 500

40 multiplied by 5

answer = 200.
