City buses have an average of 1400 daily riders. During a gas shortage, the average number was 1554. What percent did the averag
I am Lyosha [343]

Answer:

11%

Step-by-step explanation:

<em>Percentage increase = (New average- previous average)/previous average x 100</em>

<em>New average: 1554</em>

<em>Previous average: 1400</em>

Percentage increase = (1554-1400)/1400 x 100

Percentage increase = 154/1400 x 100

Percentage increase = 0.11 x 100

Percentage increase = 11%

Therefore, the average increased by 11%.
