The Nike shoes were increased from $80 to $100. By what percentage was video increased

Percentage increase formula :
X-y divided by y and multiplied by 100
100-80 equal to 20
20 over 80 is 0.25
0.25 multiplied by 100 is 25%
Hope this helps ;)

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
