<u>Both Parts
</u><u />First, we need to know what the price is 50% off. To find this, we just need to multiply 49.99 by 50%'s decimal value (0.5).
<u>
</u><u />49.99
<u>x .5
</u><u />≈25.00<u>
Part A
</u><u />To find sales tax, we should multiply the number by the percent's decimal value. In this case, it is an 8% sales tax, which has a decimal value of 0.08.
<u>
</u><u />25.00
<u>x0.08
</u><u /><u /> 0002
Using the math above, we can see that the sales tax was $2.00.
<u>Part B
</u><u /><u />To solve for this, we need to add the sales tax back to the original price.
25.00
<u>+2.00</u>
27.00
Using the math above, we can see that the total price for the headphones is $27.00.
11/16= 0.6875
So, the answer will be 11/16 < 0.688
Hope this helps!
Your answer is quite simple, really. All you have to do is divide $3.36 by 7 (The ounces of grapes he bought), and your answer should come out to be $.48, to check if this is correct, you then should add .48, 7 times, or multiply it by 7. Which, is what I did. And that should bring you to 3.36!
(39x52=2028) (3.8x62=18.62) 2028 divided by 18.62 equals (108.915145) 108.91
So Pythagorean Theorem is a^2+b^2=c^2
So, 12^2+16^2= 400
c=400, but you need to find c^2. so do the square root of 400, which is 20. so x=20
