Answer:
$18.15
Explanation:
In this case, we can add the percentages because they are taken of the same number.
The state sales tax, 4.6%, will be taken of $220, the purchase price. The county sales tax, 3.65%, will also be taken of $220, the purchase price. Since they are being taken of the same number, we can add the percentages:
4.6+3.65 = 8.25%
Now we can take 8.25% of 220:
8.25% = 8.25/100 = 0.0825
0.0825(220) = $18.15
Answer:
x=1.714285714 or x=1.71
Step-by-step explanation:
Distribute 8 to x and 8 (8x+64)
Get rid of -13x on the other side of the equation by doing +13x to both sides.
That should leave you with 21x+64=100.
Subtract 64 from both sides of the equation.
21x=36
Divide 21 from both sides which will leave you with the answer as a long decimal so round it.
x=1.71
