B. What is the total cost of the pair of boot

A~8.83;128.88
B~8.83;136.83
C~0.88;136.83
D~0.88;128.88

Answer 1

40.1%

Explanation:

I am assuming that 192 is in 100%.

100% = 192

I then represent the value that we are looking for with
`x`.

x% = 77

By dividing both equations (100% = 192 and x% = 77) and remembering that both left hand sides of BOTH equations have the percentage unit (%).

`(100)/(x) = (77)/(192)`

Now, of course, we take the reciprocal, or inverse, of both sides:

`(x)/(100) = (7)/(192)`

x = 40.1%

Thus making the answer: 40.1% of 192 is 77.
