Answer:
1966600 items must be produced in other to profit $3933
Step-by-step explanation:
from the equation y = 0.002x -0.20
where y is the profit in dollars
and x is the number of items
then to get the number of item to be produced in other to profit $3933 ?
will be by substituting $3933 for y in the equation and solving for x,
3933 = 0.002x - 0.20
Firstly you will add 0.20 to both sides, which will be
3933 + 0.20 = 0.002x - 0.20 + 0.20
3933.20 = 0.002x
then we will divide both sides by 0.002
3933.20 / 0.002 = 0.002x / 0.002
therefore, x = 1966600
Answer:
1
Step-by-step explanation:
0=1-x
-1= -x
divide both sides by -1
x=1

Answer:
175 dimes and 75 quarters
Step-by-step explanation:
Make a system of equations, where d is the number of dimes and q is the number of quarters:
d + q = 250
0.1d + 0.25q = 36.25
Solve by elimination by multiplying the top equation by -0.1:
-0.1d - 0.1q = -25
0.1d + 0.25q = 36.25
0.15q = 11.25
q = 75
Then, plug in 75 as q into one of the equations to solve for d:
d + q = 250
d + 75 = 250
d = 175
So, there are 175 dimes and 75 quarters
