Answer:
Eduardo's second statement is wrong.
Step-by-step explanation:
Eduardo says that an increase from 10 to 40 is 300% which is true. Because there is an increase by (40 - 10) = 30 and the percent of increase is calculated with respect to 10.
So, % of increase = [tex]\frac{30 \times 100}{10} = 300[/tex]%.
But when we consider a decrease from 40 to 10, then the decrease is by (40 - 10) = 30, but the percent of decrease will be calculated with respect to 40.
Therefore, the % decrease = [tex]\frac{30 \times 100}{40} = 75[/tex]%.
Hence, Eduardo's second statement is wrong. (Answer)
