John bought 3 pencils for $0.75 each and a notebook for $4.25. If the tax rate is 5%, what is the total amount of John's purchase including the tax?

$6.83

Step-by-step explanation:

First calculate the before-tax total amount:

$0.75 + $0.75 + $0.75 + $4.25, or

3($0.75) + $4.25 = $2.25 + $4.25 = $6.50    (total before tax)

The before-tax total PLUS the 5% tax comes to:

$6.50 + 0.05($6.50) = $6.50 + $0.33  =  $6.83

is only a line? i think so
