Application of Percents - Portion Formula :

Application of Percents - Portion Formula Portion (P) = Base (B) x Rate (R) Portion “is” Base “of” Rate “%”

Solving for Portion :

Solving for Portion Sales of McDonalds drive-thru customers are 60% of total sales. Total sales are $1,600,000. What are the drive-thru sales? Portion = Base x Rate
P = $1,600,000 x .60
P = $960,000

Solving for Rate :

Solving for Rate Sales of McDonalds drive-thru customers are $960,000. Total sales are $1,600,000. What Percent of customers eat in the restaurant? Rate = Portion
Base
R = $640, 000
$1,600,000
R = 40% $1,600,000
- 960,000

Solving for Base :

Solving for Base Sales of McDonalds drive-thru customers are 60% of total sales. Sales of eat-in customers are $640,000. What are total sales? Base = Portion
Rate
B = $640,000
.40
B = $1,600,000 eat in sales Percent of customers that eat-in (1.00 - .60)

Rate of Percent Decrease :

Rate of Percent Decrease 15 oz. Rate = Portion
Base Rate = 12
15 Amount of Decrease (P) Original Weight (B) .80 or 80%
Decrease 3 oz. Original New Percent of Decrease (R)

Rate of Percent Increase :

Rate of Percent Increase $1,000 Rate = Portion
Base Rate = $1,500
$1,000 Original sales (B) 1.5 or 150%
Increase $2,500 Original New Amount of Increase (P) Percent of Increase (R)
