Problema Solution
Due to an ice storm, the price of oranges increased from .69 a pound to 1.99 a pound from one year to the next. What is the percent of increase rounded to the nearest tenth?
Answer provided by our tutors
the formula for percent of change (increase or decrease) is difference divided by original times 100
in this case the difference is given by 1.99 - .69, which is equal to 1.3
the original is the .69
so you have 1.3 / .69
which equals 1.88405
1.88405 * 100 = 188.405
round this to the nearest tenth to get a 188.4% increase
