Question

Ms Campbell bought 2 table lamps for $42 with tax included .if each lamp costs $20 before tax was added, what tax rate did she pay on the two lamps

Answer 1

Answer:5%

Explanation:

Given, cost of two table lamps including tax = $42

Therefore, cost of one table lamp including tax =
`(42)/(2)`=21$

Given, cost of one table lamp before tax = $20

Hence tax amount on each lamp = $21 - $20 = $1

Hence tax rate payed
`=\frac{\text {tax amount}}{\text {Sale Price}}* 100`

`=(1)/(20)* {100}=5\%`
