Lesson Plan

Solve percent increase and decrease problems by treating the new value as the growth factor times the original

Convert between a percent change and its growth factor, including changes of 100% or more worded as a percent of the original or as a percent more than it

Find the percent change between two values as the growth factor, new ÷ original, minus 1

"Use percentages to solve problems in a variety of contexts: • including those that involve percent increases and decreases for many different quantities." "Understand and use the relationship between percent change and growth factor (5% and 1.05, for example); include percentages greater than or equal to 100%." "• including, but not limited to, discounts, interest, taxes, and tips." → sat-psda-pct-calc
