Answer:
200 units
Step-by-step explanation:
The total income must be at least equal to the costs, and that is:
10*U = 5*U + 1000 Solving for U, which is the amount of units sold per month:
U = 1000/5 = 200 units.
Answer:

Step-by-step explanation:
The method of variable substitution is a way of solving a system of equations. It involves solving one equation for a variable and then substituting in the expression that represents the value of the solved variable into the other equation. After doing so, one can solve for the unknown variable and then backsolve for the other variable.

In this system, the second equation is already solved for (y), thus one can substitute that expression into the other equation in the system.

Now solve using inverse operations,

Backsolve to find the value of (y), substitute in the value of (x), and solve for the value of (y).

Substitute,

Solve,

Thus, the answer to this system of equations is the following,
.
Add 10 to both sides to cancel out the 10
divide 2 on both sides
X= 18
Answer:
m=0.18b+4
She'll earn $10.30
Step-by-step explanation:
m=0.18b+4
m=0.18(35)+4
m=6.3+4
m=10.3
2x+8–10=22
2x=24
x=24/2
x=12
yes! you’re absolutely right, i hope i helped you
