Arturiano [62]

Incomplete Question:

The content of the pie chart is as follows:

<em>Hamsters  = 9% ; Snakes  = 10% ; Cats  = 23% </em>

<em> Birds  = 21% ;  Dogs  = 26% ;  Fish  = 11%</em>

<em></em>

Answer:

The number of citizens who chose cat or fish is 47,600

Step-by-step explanation:

Given

Number of citizens = 140,000

Required

Determine the number of those that chose fish or cats

First, we need to calculate the percentage of those whose pets are either cats or fish

Percentage = Cat + Fish

Substitute 23% for cat and 11% for fish

Percentage = 23\% + 11\%

Percentage = 34\%

Next, is to multiply the calculated percentage by the number of citizens

Cat\ or\ Fish = Percentage * Number\ of\ Citizens

Cat\ or\ Fish = 34\% * 140000

Cat\ or\ fish = 47600

<em>Hence, the number of citizens who chose cat or fish is 47,600</em>
