Answer:
100/79% or abt 126.5% is the increase so it rises 26.5%
Step-by-step explanation:
100% is the original price
so 100 - 21 = 79
that means it's now 79% of what it was
so multiply by 100/79% to find what you have to multiply by to get the original price
this is 126.5%
the original was 100% so the increase is 126.5 - 100 is 26.5%, your final answer
