Question

A mobile device that normally sells for $99.90 is marked down 10%. What's the discount price?

Answer 1

Given:

a.) A mobile device that normally sells for $99.90

b.) It was marked down by 10%.

To be able to determine the discount price, we will be using the following formula,

`\text{ Discount Price = Original Price - (Original Price x }\frac{\text{Mark Down Percentage}}{100}\text{)}`

We get,

`\text{ Discount Price = Original Price - (Original Price x }\frac{\text{Mark Down Percentage}}{100}\text{)}`
`\text{ = \$99.90 - (\$99.90 x }(10)/(100))`
`\text{ = \$99.90 - (\$99.90 x }0.10)`
`\text{ = \$99.90 - \$9.99}`
`\text{ Discount Price = \$89.91}`

Therefore, the discount price is $89.91
