I believe it would be around 117.18
The function for x=3 is 1
0.05x+0.02(2000-x)=77.5
0.05x+40-0.02x=77.5
(0.05-0.02)x=77.5-40
0.03x=37.5
X=37.5/0.03=1250 at 2%
2000-1250=750 at 5%
Answer:
The first number is
72.6
Step-by-step explanation:
Let second number be x.
First number= 6x
Third number= 3x
According to question,
6x+x+3x=121
or, 10x=121
or,x=121/10=12.1
First number= 6x=6×12.1=72.6
Third number=3x=3×12.1=36.3
If the tax was 10%, then you’d end up paying the original 100% plus the additional 10% tax, so you’d pay 110% of the original price.
In your example, it’s the same, except you have 8.25% tax, so you’d pay 100%+8,25% or 108.25% of the original price.
That’s stated as a percent.
To convert a percent to a decimal, you divide by 100:
108.25 ÷ 100 = 1.0825
To convert a decimal to a fraction, you have to know the place value of the smallest place. In this case, the 5 is in the ten thousandths place.
10825/10000
You can always double check that fraction on a calculator.
