A person wanted to purchase products at a store ($43.99) and wanted to use a coupon for 20% off. What would be the final total when the coupon is used on the item and the sales tax (11%) is added? Remember significant figures in your calculations.
43.99*.8*1.11= ?
Should be rounded to nearest cent. The 20 percent is significant to many places. All others are to nearest cent.
(43.99)-(43.99*0.20)+(43.99*0.11)=?????
Bobpursley has a typo!!!!!
To anonymous--- I don't think so but you have one. Anonymous added tax to the 43.99 which is the initial price. Tax usually is charged on the final price. Also note that 43.99-(43.99*0.20) is the same as 43.99*0.8.
You are correct......
To calculate the final total after applying the coupon and adding the sales tax, you can follow these steps:
Step 1: Calculate the discount amount:
To find the discount amount, multiply the original price ($43.99) by the coupon percentage (20% or 0.20).
Discount = $43.99 * 0.20 = $8.798
Step 2: Subtract the discount amount from the original price to find the discounted price:
Discounted price = $43.99 - $8.798 = $35.192
Step 3: Calculate the sales tax amount:
To calculate the sales tax, multiply the discounted price by the sales tax percentage (11% or 0.11):
Sales tax = $35.192 * 0.11 = $3.87112
Step 4: Add the sales tax amount to the discounted price to obtain the final total:
Final total = $35.192 + $3.87112 = $39.06312
Rounding to the appropriate number of significant figures would depend on the specific rules or guidelines you are following. In this case, assuming you only need two significant figures, the final total would be $39.06.
Therefore, the final total amount, after applying the coupon and adding the sales tax, would be $39.06.
