Question

Luke bought a pair of jeans originally priced at $69.00. The jeans have been marked down 25%, and a sign posted on the rack where he found them says, “10% additional discount given at register.” Which calculation will give the price that Luke will pay for the jeans, not including sales tax?

A. 69(0.35)
B. (0.65)
C. 69(0.75)(0.90)
D. 69(0.25)(0.10)

Answer 1

Answer: C. 69(0.75)(.0.90)

Explanation:

In order to find a discounted price you subtract the discount percentage as a decimal from 1 and multiply the outcome to the original price. For this case, 1-0.25=0.75 and 1-0.1=0.90. So your equation will be 69(0.75)(0.90)

Answer 2

Option C .

Explanation:

It is given that,

Original price of jeans = $69.00

Marked down = 25%

Additional discount = 10%

We need to find the price that Luke will pay for the jeans, not including sales tax.

`\text{New price}=69(1-\text{Marked down})(1-\text{Additional discount})`

`\text{New price}=69(1-25\%)(1-10\%)`

`\text{New price}=69(1-(25)/(100))(1-(10)/(100))`

`\text{New price}=69(1-0.25)(1-0.10)`

`\text{New price}=69(0.75)(0.90)`

Therefore, the correct option is C .
