In a Local boutique you intend to buy a handbag with original price $38 a jacket with original price of 189 and a scarf with original price $23 currently the store is running a promotion for 30% off entire store in addition as a store loyalty card member you’re entitled to an extra 10% off all sales price the state charges a 5% sales tax on all purchases which is the final purchase price of the items including all discounts and sales tax write your answer to

In the question, we are asked to work with percentages. We know that the person had bought three items of a total of 250 dollars (38 + 189 + 23). We are told that the items have a 30% discount, another 10% discount on that and a 5% tax increase on all of that.

First, let's work with the 30% discount. The official way of working out the problem you would use the unitary method. The unitary method is when we divide the total cost by 100. So 250/100, is 2.5. We multiply this by the remaining percent (100%- 30%=70%) so 2.5*70 is 175.

Then, we work with ten percent. The only difference is that instead of using the original price with are using the 30% discounted price. If we use the unitary method again we find that 175/100 is 1.75 and that multiplied by 90 (because we are only subtracting the 10% not 30%) is 157.50.

Finally, we do the same for the 5% percent only difference being we add it to 157.50. 157.50/100 is 1.575 and multiplied by 105 (because we are adding 5% onto 100% so it becomes 105%).

The final answer is 165.375 and when rounded to the nearest cent it becomes $165.38.
