Solving a system of equations, we conclude that they sold 20 bags of chips and 5 fruit snacks.
How to find the number of bags of chips sold and fruit snacks sold?
First, let's define the variables:
- x = number of bags of chips sold.
- y = number of fruit snacks sold.
Now we know that they sold 15 more bags of chips than fruit snacks, then:
x = y + 15
We also know that they made a total of $42.50
Then we can write the system of equations:
x = y + 15
x*$1.75 + y*$1.50 = $42.50
To solve that, we can replace the first equation into the second one to get:
(y + 15)*$1.75 + y*$1.50 = $42.50
$26.25 + y*$3.25 = $42.50
y = ($42.50 - $26.25)/$3.25 = 5
And we know that x is equal to y plus 15, then:
x = 15 + y = 15 + 5 = 20
Then we conclude that they sold 20 bags of chips and 5 fruit snacks.
