is given by:
That means 60% of the original value.
Now we have another discount of 45% for the 60% reamining after a 2 discount so let's

So the discount is 33% and we are paying 67% of the value. The reason is given by the relative change:
Answer:
Around 67
x=67
Step-by-step explanation:
90 over 100 equals 60 percent over x
60*100/90=
6000/90=
66.66666666666666 (more sixes continue on)
7x = 1 + 2x
1. Subtract 2x from both sides
5x = 1
2. Divide it all by 5
<em><u>x = 1/5</u></em>
<em><u>SO X EQUALS TO 1/5.</u></em>
