Answer:
The first option.
Because we're solving for the price of each gallon, x will represent the cost of each gallon. Since 8.4 is the total amount of gallons, multiply 8.4 and x to get $23.94. Solve for x by dividing 23.94 to get $2.85 per gallon. To check this, substitute 2.85 for x into the equation: 8.4 (2.85) = 23.94

Answer:
12 bags of chips
5 candy bars
Step-by-step explanation:
We will first make two different equation. The first one for the money made, and the second one for the amount sold. X will refer to the chips and Y will refer the candy bars.

Now I will multiply the second equation by -1 so that I can cancel out.

Solve for x

This is how many chips she sold.
Now plug this number into one of the first two equations.

This is how many candy bars she sold.
Hope this helps! <3
