A flooring installer measures 850 sq ft of floor and adds 8% for waste. How many square feet of flooring should be ordered?
Answer in sq ft.
918 sq ft
Waste: 0.08 × 850 = 68 sq ft. Order: 850 + 68 = 918 sq ft (or 850 × 1.08).
Reference: Adding a percentage: total = quantity × (1 + percent ÷ 100)
An inspector rejects 12 welds out of 150. What percent of the welds were rejected?
Answer in %.
8 %
12 ÷ 150 = 0.08. 0.08 × 100 = 8%.
Reference: Percent = (part ÷ whole) × 100
A cordless drill kit lists at $64.00 and a supplier offers a 20% trade discount. What is the discounted price?
B. $51.20
Discount: 0.20 × 64 = $12.80. Price: 64.00 − 12.80 = $51.20. $12.80 is only the discount amount, and $44.00 treats 20% as 20 dollars.
Reference: Percent discount: price = list × (1 − percent ÷ 100)
