Question

When the pilgrims counted noses, they got a count that was 128 percent too high. If they counted 9120 noses, what was the correct count? 

Answer 1

If a number is 128 percent too high, that means it is 228 percent of the actual number.

So set up a ratio and cross multiply.

 

9120 / 228 = x / 100

 

912000 = 228x

 

x = 4000

 

 

Answer 2

1.28n = 9120

n = 7125

 

Boom.
