Question

2. SALES TAX Suppose that a state sales tax is 7%. Make a table showing the

amount of tax on items with prices of $6, $8, $10, and $12. How can you
find whether the price and amount of sales tax are linearly related?

Answer 1

$6 * .07= 0.42 tax

6+042= $6.42

$8*.07=0.56 tax

8+.56= $8.56

$10*.07=0.70 tax

10+0.70=$10.70

$12*.07=0.84 tax

12 + 0.84=$12.84
