1. We assume, that the number 128 is 100% - because it's the output value of the task.
<span>2. We assume, that x is the value we are looking for. </span>
<span>3. If 128 is 100%, so we can write it down as 128=100%. </span>
<span>4. We know, that x is 51% of the output value, so we can write it down as x=51%. </span>
5. Now we have two simple equations:
1) 128=100%
2) x=51%
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:
128/x=100%/51%
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 51% of 128
128/x=100/51
<span>(128/x)*x=(100/51)*x - </span>we multiply both sides of the equation by x
<span>128=1.96078431373*x - </span>we divide both sides of the equation by (1.96078431373) to get x
<span>128/1.96078431373=x </span>
<span>65.28=x </span>
x=65.28
<span>now we have: </span>
<span>51% of 128=65.28</span>
y=45x+200
y is the total cost, x is the number of months, and 200 is the start.
Answer:
£10,737,418.24
Step-by-step explanation:
<u>Every day amount doubles:</u>
- March 1st = 1p= 2^0 p
- March 2nd = 2*1p = 2^1 p
- March 3rd = 2*2p = 2^2 p
- ...
- March 31st = 2^30 p = 1,073,741,824 p = £10,737,418. 24

Answer:
7/25
Step-by-step explanation:
there are 14 numbers greater than 30 and less than 45
