Answer:

<u>145 people were surveyed</u>

Step-by-step explanation:

1. Let's review the information given to answer the question correctly:

Percentage that indicated they preferred walking to running = 90%

2.  If 130 people preferred running to walking, how many people where surveyed?

For answering this question, we will use the Rule of Three simple, this way:

x = Number of people surveyed

90 * x = 130 * 100

90x = 13,000

x = 13,000/90

x = 144.44

But we need a whole number for an accurate answer, so we round the value of x to the next whole number.

<u>145 people were surveyed</u>
