Question

a store offers a discount of 20% off the original price of an item. which equation represents the discounted price (d) of an item originally priced at $50?
a. $d = 50 - (0.20 \times 50)$
b. $d = 50 \times 0.20$
c. $d = 50 + (50 \times 0.20)$
d. $d = 50 - 0.20$

a freelancer charges $15 per hour and a $10 transportation fee. what equation models the total payment p for h hours of work?
a. $p = 10 + 15h$
b. $p = 15h - 10$
c. $p = 25h$
d. $p = 15 + 10h$

Explanation:

First Question Step1: Calculate discount amount

Discount = $0.20 \times 50$

First Question Step2: Find discounted price

$D = 50 - (0.20 \times 50)$

Second Question Step1: Calculate hourly charge

Hourly charge = $15h$

Second Question Step2: Add transportation fee

$P = 10 + 15h$

Answer:

a. $D = 50 - (0.20 \times 50)$
a. $P = 10 + 15h$
