If 210 people say pizza is their favorite food,how many people were surveyed using the graph if 42% chose pizza, 33% chose hotdogs, and 25% chose pasta?
0.42x = 210
Solve for x.
To find out how many people were surveyed using the given information, we can use the concept of percentages.
First, let's calculate the number of people who chose pizza as their favorite food.
If 42% of the surveyed people chose pizza, we can calculate it by multiplying the total number of people surveyed by the percentage that chose pizza:
42% of X = (42/100) * X
Next, let's calculate the number of people who chose hotdogs and pasta respectively using the same method.
33% of X = (33/100) * X (people who chose hotdogs)
25% of X = (25/100) * X (people who chose pasta)
Since the total number of people surveyed is equal to the sum of people who chose pizza, hotdogs, and pasta, we can add the three values together to find X.
So, the equation becomes:
(42/100) * X + (33/100) * X + (25/100) * X = 210
After calculating the equation, we find that X is equal to 600.
Therefore, based on the graph, it can be assumed that 600 people were surveyed.
