A box of chalk and 2 staplers cost $10. three boxes of chalk and 2 staplers cost $18. find the total cost of 1 box of chalk and
Alchen [17]
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.

An apartment building caretaker puts 0,75 L of chlorine into the swimming pool every day. If the chlorine is sold in containers
kaheart [24]

the question says,

the apartment caretaker puts 0.75L of chlorine into the swimming pool daily

the chlorine is sold in containers that holds 4L

so we should get the numbers of containers he should order in 120days.

first of all, lets get the total chlorine needed

total chlorine needed = the chlorine he pours daily X the number of days

total chlorine needed = 0.75 X 120 = 90L

to get the number of containers he should order

= 90/4

= 22.5

therefore the number of containers the he sholuld order in 120 days is 22 and half container.
