Answer:
5 $20 bills and 7 $10 bills
Step-by-step explanation:
You need to have 12 bills, and their values must add up to $170. Start with a guess, and adjust the guess until you find the answer.
The total number of $20 bills and $10 bills must be 10.
I made a table below. I started with a guess and kept adjusting it.
Number of Number of Total
$20 bills $10 bills Value
8 ($160) 4 ($40) $200 Value is too high.
6 ($120) 6 ($60) $180 Value is close
5 ($100) 7 ($70) $70 Correct value
Answer: 5 $20 bills and 7 $10 bills
Answer:
$18,570.7425
Step-by-step explanation:
24,000 * 0.95 5 times, this will give you the 5% for 5 years
To get the solution, we are looking for, we need to point out what we know.
<span>1. We assume, that the number 150 is 100% - because it's the output value of the task. </span>
<span>2. We assume, that x is the value we are looking for. </span>
<span>3. If 150 is 100%, so we can write it down as 150=100%. </span>
<span>4. We know, that x is 16% of the output value, so we can write it down as x=16%. </span>
5. Now we have two simple equations:
1) 150=100%
2) x=16%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
150/x=100%/16%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 16% of 150
150/x=100/16
<span>(150/x)*x=(100/16)*x - </span>we multiply both sides of the equation by x
<span>150=6.25*x - </span>we divide both sides of the equation by (6.25) to get x
<span>150/6.25=x </span>
<span>24=x </span>
x=24
<span>now we have: </span>
<span>16% of 150=24</span>
