medium box has best value
A system of linear equations is a set of two linear equations with two variables.
Here is the solution of the given problem above:
Let s= staples
<span>c = chalk</span>
<span>c + 2s = 10 </span>
<span>3c + 2s = 18 </span>
<span>-c-2s = -10 </span>
<span>3c + 2s = 18 </span>
<span>2c = 8 </span>
<span>c = 4 </span>
<span>s = 3
</span>Therefore, the price per chalk box is $4 and per stapler is $3.
So the total cost of the chalk and stapler would be $7.
Hope this is the answer that you are looking for. Thanks for posting it here in brainly.

Answer:
They will not have the same weight during the program
Step-by-step explanation:
Let x be the number of weeks.
<u>Sandra:</u>
Sandra is starting at 150 pounds and plans to lose 1 pound a week.
Weight after x weeks:

<u>Bernice:</u>
Bernice is starting at 135 pounds and plans to lose 1/2 a pound a week.
Weight after x weeks:

Weights must be the same, so

Since 30 weeks is more that 12 weeks (the duration of the program), they will not have the same weight during this program.
