Find the percent change from 48 to 228. Tell whether it is a percent increase or decrease. If necessary, round your answer to the nearest percent.

If it is going from a smaller number to a larger number, then it is a percent increase

percent increase = (new number - original number) / original number ... * 100

= (228 - 48) / 48 ... * 100

= 180/48 ... * 100

= 3.75 * 100

= 375% increase <===
