Problema Solution
The cost of an item is reported to have decreased 400% during the past 10 years, does that mean that the cost is four times lower than the original cost?
HINT: use actual numbers to figure it out. For example, take the original cost to be $200.00
Answer provided by our tutors
the original cost is $200.00
let the decreased cost to be x
200 is 400% bigger then x
(400*x)/100 = 200
x = $50
200/50 = 4
the cost is 4 times lower than the original cost.
