The order pair below is a solution to which equation (24,6)

1 answer:

7 0

It would be much easier for me to help you pick the correct equation
if you would let me see the list of choices.

Since I can't see any of the choices, I'll just make up a few equations
that have the ordered pair (24, 6) as a solution:

   Y = 0.25 x

   Y = x - 18

   Y = 0.5 x - 6

   Y = 0.1 x + 3.6

Suppose a movie theater you work at sells popcorn in three different sizes. A small costs $2, a medium costs $5, a large costs $

Answer:

$\left \{ {{{s+m+l=250}} \atop {2s+5m+10l=1726 \atop {l=2s} \right.$

Small popcorns: 68

Medium popcorns:: 46

Large popcorns: 136

Step-by-step explanation:

<h3>The complete exercise is: "Suppose the movie theater you work at sells popcorn in three different sizes. A small costs $2, a medium costs $5, and a large costs $10. On your shift, you sold 250 total containers of popcorn and brought in $1726. You sold twice as many large containers as small ones. How many of each popcorn size did you sell?" </h3><h3 />

Let be "s" the number of small popcorns you sold, "m" the number of medium popcorns syou sold and "l" the number of large popcorns you sold.

Set up a system of equations:

$\left \{ {{{s+m+l=250}} \atop {2s+5m+10l=1726 \atop {l=2s} \right.$

To solve it:

- Multiply the first equation by -5 and add it to the second equation:

$\left \{ {{-5s-5m-5l=-1250}} \atop {2s+5m+10l=1726 \right. \\..................................\\-3s+5l=476$
