18%

Step-by-step explanation:

We know that currently 20% of city employees ride the bus to work. The problem states that there was a 10% increase from last year. To figure out this answer, we need to find out how much 10% of 20% is. Knowing what we know, lets now convert the percentages to decimals so we can do this math easier.

- 20% converted to a decimal is 0.2

- 10% converted to a decimal is 0.1

To find 10% of 20%, we simply multiply (0.2) x (0.1) which equals 0.02. In other terms, this is 2%. We now know that since last year, the percentage of city employees riding the bus went up 2%. This means that if we simply subtract 2 from 20 we get 18 ...

Last year, 18% of city employees rode the bus to work.
