Answer:

$104.64

Step-by-step explanation:

Because coupons come before tax, we have to take <em>away</em> 20%, then <em>add</em> 9%

Step 1 : Find 20%

In order to find the percent of anything, all you have to do is multiply the percent (as a decimal) by your price

In this case, it's :  120 × 0.20

Using this expression, we find that 20% of $120 = $24

Step 2 : take <em>away </em>20%

Coupons take away money from a full price, so we will take away $24 from $120, leaving us with $96

Step 3 : Find 9%

Now we multiply 0.09 (9%) by our <em>new</em> price (96)

96 × 0.09 = $8.64

Step 4 : Add 9%

Lastly, we use our coupon-added price (96) and add our tax (8.64)

96 + 8.64 = $104.64

The weight of an object on a particular scale is 145.2 lbs. The measured weight may vary from the actual weight by at most 0.3 l
joja [24]

1. Know what you're looking for:

The range is the difference between the lowest and highest values.

Your weight is 145.2 and can vary from the actual weight by maximum 0.3 lbs less or maximum 0.3 lbs more.


2. Calculate your lowest and highest values :


Lowest : 145.2 - 0.3 = 144.9 lbs

Highest : 145.2 + 0.3 = 145.5 lbs


3. Calculate the range of actual weights of the object :


145.5 - 144.9 = 0.6 lbs


--> The answer is: <u>The range of actual weights of the object is 0.6 lbs.</u>


There you go! I really hope this helped, if there's anything just let me know! :)
