Question

PLEASE HELP!!

Answer 1

For this you have to make two proportions that are $\frac{part}{whole}$ and set them equal to each other.

The first proportion represents the percent of people who like silver as their favorite car color

Since this is a circle graph the whole will always be 100 because percents are always taken out of 100

The part would be 10 because only 10% out of the 100% like silver

The second proportion is the people that represent the response.

350 would be the whole because that is the total amount of people surveyed

The part is unknown and what you are solving for.

Here is how the proportion should look like:

$\frac{10}{100} = \frac{x}{350}$

Cross multiply (If you don't know what this is look at the image below to see my work)

The cross multiplication will give you:

3500 = 100x

Isolate x by dividing 100 to both sides

3500/100 = 100x/100

35 = x

This means that 35 people out of the 350 surveyed like silver cars

Hope this helped!
