1.) You are either adding 6% of the item’s cost onto the sticker price,

or

2.) Finding 106% of the cost of the item

Say it costs $10

1.) $10

x 0.06 {finding 6% of the item’s cost}

—————-

$0.60 in tax {changed 6% to decimal and multiplied to get the amount of tax}

10 + 0.60 = $10.60 {added the tax onto the item cost}

An expression for that would be

**a + 0.06a** if the item costs $a

————————————————————————————-

2.) $10 x 1.06 {finding 106% of the cost of the item}

= $10.60 with tax {multiplied by 106% to find the total cost including tax}

An expression for that would be

**1.06a** if the item costs $a
