Answer 1

$0.14 will be the sales tax on an item that costs $1.60.

Explanation:

We can see from the table given that sales tax is increasing in equal proportion with increase in the price i.e. sales tax is directly proportional to price.

We can use the unitary method to calculate the sales tax on an item which has a price of $1.60.

It is given that $0.35 is the sales tax on an item which has a price of $4.

Sales tax on price of
`\$4 = \$0.35`

Sales tax on price of
`\$1 = (0.35)/(4)`

Sales tax on price of
`\$1.60 =`
