The answer is D. 6.00 in. because 2.25 plus 3.75 equals 6.
Answer: The cost of a pencil and a pen is 8 cents
Note the equal sign. What you do to one side, you do to the other. Isolate the x.
Subtract 4 from both sides
x + 4 (-4) = 11 (-4)
x = 11 - 4
x = 7
7 is your answer for x.
hope this helps
Answer:
8.25
Step-by-step explanation:
Plug in 8.25 where x is. Then according to PEMDAS you add everything up in the parenthesis then multiply the sum of that by 7/3.
By law, sales tax is calculated on the discounted price of the shirts. Would the total cost of the shirts including the 6.5% sales tax be greater if the tax was applied before a 20% discount is taken, rather than after a 20% discount is taken?
Answer:
They will be the same
Step-by-step explanation:
<u>Sales tax applied before</u>
Total costs before discount = (2*$ 10.98)+$ 11.50+(2*$ 15.99)=$ 65.44
Discount of 20% will be ![\frac {20}{100}\times 65.44=$13.088](https://tex.z-dn.net/?f=%5Cfrac%20%7B20%7D%7B100%7D%5Ctimes%2065.44%3D%2413.088)
New price= 65.44-13.088=$52.352
Adding 6.5% sales tax we obtain ![\frac {6.5}{100}\times 52.352=$3.40288](https://tex.z-dn.net/?f=%5Cfrac%20%7B6.5%7D%7B100%7D%5Ctimes%2052.352%3D%243.40288)
Total payment= 52.352+3.40288=55.75488
<u>Sales Tax applied after</u>
If 20% is taken after sales tax then the sales tax of 6.5 amounts to
![\frac {6.5}{100}\times 65.44=4.2536](https://tex.z-dn.net/?f=%5Cfrac%20%7B6.5%7D%7B100%7D%5Ctimes%2065.44%3D4.2536)
New price= 65.44+4.2536=$ 69.6936
Then 20% discount is ![\frac {20}{100}\times 69.6936=13.93872](https://tex.z-dn.net/?f=%5Cfrac%20%7B20%7D%7B100%7D%5Ctimes%2069.6936%3D13.93872)
Discounted price after sales tax= 69.6936-13.93872
=55.75488
Both systems come to the same value hence there's no difference
