Section 3.3 Finding Base

Formula for Base… P B R Remember… P = B x R to find PART Use B = P ÷ R To find Base (Base = Part divided by Rate) P B R

EX: solve for base 1. 36 is 10% of _____ 2. 91 is 5% of _____

Examples from p 104 30. In analyzing the success of driver’s license applicants, the state finds that 58.3% of those examined received a passing mark. If the records show that 8370 new driver’s licenses were issued, what was the number of applicants? Round to the nearest whole number.

34. Telecommunications equipment maker Nortel Networks says it will lay off 4000 workers globally. If this amounts to 4% of its total workforce, how many workers will remain after the layoffs?

36. A casino hotel in Barbados states that 45% of its rooms are for non-smokers. If the resort allows smoking in 484 rooms, find the total number of rooms.
