Because all bills have the same height, you can compare the number of bills in each stack directly to determine the percent increase in height. The number of $20 bills in a stack with a value of $1,600 is: 1600/20 = 80 The number of $10 bills in a stack with a value of $1,050 is 1,050/10 = 105
Plug these values into the percent change formula to evaluate Quantity A:
A=5/16
5/16<33.5
B is the answer
