Question

8. A store sold 4 times more chocolate bars than Skittles. Combined, they sold 30 items. The system below

represents the situation:
c=4s
c+s=30
How many chocolate bars were sold?

Answer 1

To solve this system of equations and find out how many chocolate bars were sold, we'll first use the equations given:

1.
`\( c = 4s \)` (where
`\( c \)` represents the number of chocolate bars and
`\( s \)` represents the number of Skittles)

2.
`\( c + s = 30 \)`

We can substitute the first equation into the second equation to solve for one of the variables. Let's substitute
`\( c \)` from the first equation into the second equation:

`\( 4s + s = 30 \)`

Now, let's solve for
`\( s \)`.

The solution for
`\( s \)` (number of Skittles) is 6. To find out the number of chocolate bars sold, we substitute this value into one of the original equations. Let's use the first equation,
`\( c = 4s \)`:

`\( c = 4 * 6 \)`

The number of chocolate bars sold was 24.
