gary goes to a store and buys a pencil originally priced at $45. the store is running a discount of 20%. what is the price of the pencil after the discount? the sales tax rate is 6.9%. tax is applied to the discounted price of the pencil. how much tax will gary have to pay?
Answer
Explanation:
Step1: Calculate discounted price
The discount is 20%, so the price after discount is $(1 - 0.20)\times45$. $0.8\times45 = 36$
Step2: Calculate tax amount
The tax rate is 6.9% or 0.069, and tax is applied to the discounted - price. So the tax amount is $0.069\times36$. $0.069\times36=2.484$
Answer:
The price of the pencil after the discount is $36. The tax Gary has to pay is $2.484.
