C. 85%
Set up the proportions
136/160 = ?/100
Then cross multiply.
100 x 136 = 13600
13600/160 = 85
Also you could use process of elimination. 296% wouldn’t work because that’s saying 136 is almost 3 times as many as 160. The other answers wouldn’t work because it’s clear that 136 is more than half of 160.
