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
For this case you can solve the problem by applying a simple rule of three in which we have
520 ---> 100%
800 ---> x
Clearing x we have
x = (800/520) * 100 = 154%
the percentage increase in cost was
154-100 = 54%
answer
the percentage increase in cost was 54%
