Answer:
% increase = 25.00125006%
Explanation:
We can solve the problem using the percentage change formula, which is given by:
% change = [(New Value - Old Value) / Old Value] * 100
Thus, we can find the percent increase by substituting 199.99 for the old value and 249.99 for the new value:
% change = [(249.99 - 199.99) / 199.99] * 100
% change = (50 / 199.99) * 100
% change = 5000 / 199.99
% change = 25.00125006
Therefore, the percent increase in the cellphone price is about 25%.
- You can either use the exact answer or the rounding answer, depending on whichever number your teacher is used to.
