Question

1. State whether the change is increasing or decreasing. Round your percent of change to the nearest integer percent. old: $49.60 new: $38.10 23% increase -23% decrease 30% increase -30% decrease

Answer 1

We have two values:

Old = $49.60

New = $38.10

Then, if we need to find if the change is increasing or decreasing, we have to use the following expression:

We have that the subtraction in the numerator is negative (the new value is smaller than the old value). Then, we finally have a decrease in change.

If we round the result to the nearest integer, we have that we have a decrease of -23%.
