What is 35% more than $870

Answers

We can think about percentages in two ways: 
1. We want to multiply 870 by 35% and then add it to 870
2. We can skip a step and just multiply 870 by 135%

1.35 * 870 = 1174.5

$1,174.5 is 35% more than $870
870(1.35)=1174.5, You would do this because 35% more of something requires 100% of something plus the 35% so 1.35 is 135%
