A box of chalk and 2 staples cost $10. Three box of chalk and 2 staplers cost $18. Find the total cost of 1 box of chalk and 1 stapler.
staples --- s
chalk -----c
c + 2s = 10
3c + 2s = 18
subtract them
2c = 8
c = 4
back into the first ---> 4+2s = 10 , s = 3
so c+s = 4+3 = 7
1 box of chalk is $4 and one stapler is $3
$10

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 1 stapler.
I don't really know
To find the cost of 1 box of chalk and 1 stapler, we need to set up a system of equations using the information given. Let's assume the cost of one box of chalk is "x" dollars and the cost of one stapler is "y" dollars.
From the first statement, we know that a box of chalk and 2 staples cost $10, so we can write the equation as:
x + 2y = 10 ----(Equation 1)
From the second statement, we know that three boxes of chalk and 2 staplers cost $18, so we can write the equation as:
3x + 2y = 18 ----(Equation 2)
Now, we have a system of equations consisting of Equation 1 and Equation 2. To solve this system, we can use the method of substitution or elimination. Let's use the method of substitution.
First, isolate "x" in Equation 1:
x = 10 - 2y ----(Equation 3)
Next, substitute Equation 3 into Equation 2:
3(10 - 2y) + 2y = 18
Simplify the equation:
30 - 6y + 2y = 18
-4y = 18 - 30
-4y = -12
Divide both sides of the equation by -4 to solve for "y":
y = -12 / -4
y = 3
Now substitute the value of "y" into Equation 3 to solve for "x":
x = 10 - 2(3)
x = 10 - 6
x = 4
So, the cost of 1 box of chalk is $4, and the cost of 1 stapler is $3.
Therefore, the total cost of 1 box of chalk and 1 stapler is $4 + $3 = $7.
