Question

Ava is raising money for a school trip by selling bags of chips and candy bars. The price of each bag of chips is $1.75 and the price of each candy bar is $1. Yesterday Ava made $26 from selling a total of 17 bags of chips and candy bars. Determine the number of bags of chips sold and the number of candy bars sold.

Answer 1

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.

$1.75x+y=26\\x+y=17$

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

$1.75x+y=26\\-x-y=-17\\\\0.75x=9$

Solve for x

$x=12$

This is how many chips she sold.

Now plug this number into one of the first two equations.

$x+y=17\\12+y=17\\y=5$

This is how many candy bars she sold.

Hope this helps! <3
