75% increase followed by 50% decrease is it greater than to original
IceJOKER [234]

Answer:

  • Set original amount = x

<u>After a 75% increase, it would become</u>

x + 75%x = x + 0.75x = x(1 + 0.75) = 1.75x

<u>After a 50% decrease, it would become</u>

1.75x - 50%(1.75x) = 1.75x - 0.5(1.75x) = 1.75x - 0.875x = 0.875x = \frac{7}{8} x

Because \frac{7}{8} x is less than x, the new amount would be less than the original.
