20% of city employees ride the bus to work. This is up 10% from last year. What percent of employees rode the bus to work last y
Pepsi [2]

Answer:

18.18% of employees rode the bus to work last year

Step-by-step explanation:

This question can be solved using a rule of three.

Last year, a proportion of x employees riding the bus was 100% = 1.

This year, 20% = 0.2 ride the bus, which is 100 + 10 = 110% = 1.1 of last year.

So

0.2 - 1.1

x - 1

1.1x = 0.2

x = \frac{0.2}{1.1}

x = 0.1818

0.1818*100 = 18.18%

18.18% of employees rode the bus to work last year
