In the state where Ozzie’s Office Supply is located, the sales tax on all orders is 6% of the order cost. Ozzie’s adds a shipping charge, which is calculated as a percentage of the amount after tax has been added. The percentage rate for that shipping charge varies, however, with the size of the order. The company charges one rate for orders less than or equal to $100, another for orders over $100 but not more than $500, and a third for orders over $500. From experience, you know that the final cost, including tax and shipping, is $109.18 for an order of $100, $217.30 for an order of $200, and $756.84 for an order of $700. Find the final cost for orders of $499 and $502.

We are told that rates changes with sizes. The text gives us two examples which include both costs, one for a quantity between 100 and 500, useful to calculate then for 499, and the other for a size over 500, useful for 502.

As the rate seems to be costant for each quantity, we can calculate 217,30/200 (our rate) * 499 = 542,16
Same for the other, we calculate the costant rate for seize > 500 as it folows: 756,84/700 and then multiply it for 502 = 542,76

For an order of $200, Sales tax is $12 since 6% of 200 is 12. The effective price after sales tax = $212. Final Price is $217.3. Calculating percentage increase from amount after sales tax = (217.3-212)/212 =  2.5% 
For an order of $700, Sales tax is $42 since 6% of 700 is 42. The effective price after sales tax = $742. Final Price is $756.84. Calculating percentage increase from amount after sales tax = (756.84-742)/742 =  2%

Which means for order above 100 but less than 500, final value is 2.5% higher than the amount including sales tax while for orders above 500, its 2% higher than the amount including sales tax.
Using this information

For order value of $499, Final cost is 499*1.06*1.025 =  542.16 
For order value of $502, Final cost is 502*1.06*1.02 =  542.76

Gemmie · Answer

Order Final cost After tax
<= $100 $100 $109.18 $106
$100 - $500 $200 $217.3 $212
> $500 $700 $756.84 $742

For order >$100 and <=$500:
- Shipping rate: $\frac{217.3}{212} = 1.025$ ==> 25%
- Final cost for an order of $499: 499 * 1.06 * 1.025 = 542.16

For order >$500
- Shipping rate: $\frac{756.84}{742} = 1.02$ => 20%
- Final cost for an order of $502: 502 * 1.06 * 1.02 = 542.76
