The <em>correct answer</em> is:
B) INS 38.35
Explanation:
The day with the best exchange rate is Friday; the rate is 1:6.1715. Converting 88.65£ with this rate, we have:
88.65(6.1715) = 547.103475.
Since he is charged an 8% surcharge, he gets to keep 100%-8% = 92% = 92/100 = 0.92 of this:
0.92(547.103475) = 503.335197
The day with the worst exchange rate is Wednesday, with a rate of 1:5.7012. Converting 88.65£ at this rate,
88.65(5.7012) = 505.41138. 4
0.92(505.41138) = 464.9784696
The difference between Friday and Wednesday is:
503.335197-464.9784696 = 38.3567274, or 38.35.

No. It's the ratio of 1,289 to 100 .
Also, it can be written as a fraction with whole numbers
on top and bottom, like this: 1289 / 100 .
Also, it can be written down on paper completely, using
digits and a decimal point or fraction bar. (You did that.)
Any one of these three facts makes it a rational number.
644 is 80% of the regular price, so price=644/0.8 = 805 $
