Answer: 111/250
Explanation:
0.444 = 444/1000 = 111/250
Divide the volume value by 1000, which is 0.194 .
y varies inversely with x.
Example:
If we multiply x by 2 we need to divide y by 2 too.
So,
If y = 16 and x = 1/2, find y when x = 32
Lets see, from 1/2 to 32 e need to multiply 1/2 by 64, right? So let's divide 16 by 64.
16/64 = 8/32 = 4/16 = 2/8 = 1/4
So we can say that:
If y = 16 when x = 1/2, y = 1/4 when x = 32.
2,640 this year
2,112 last year
the 1760 is 20% less than - so 120% of 1760 is the previous year:
1760 * 1.2 = 2112
2112 increased by 25% is a total of 125%:
2112 *1.25 = 2640
