Question

Daniel bought a bicycle for $80 and a helmet for $20. The sales tax was 5%. How much did Daniel pay for the two items, including tax?

Answer 1

Given:

Daniel bought a bicycle for $80 and a helmet for $20.

Sales tax = 5%

To find:

The total amount of both items including tax.

Solution:

Price of bicycle (excluding tax)=
`\$80`

Price of helmet(excluding tax) =
`\$20`

Price of both items =
`\$80 + \$20`

=
`\$100`

Now, the sales tax is 5%. So,

Price of both items (including tax) =
`\$100+(5)/(100)(\$100)`

=
`\$100+\$5`

=
`\$105`

Therefore, the Daniel pays $105 for the two items, including tax.
