Let x be the initial deposited amount.
x + 10 will be the final amount
x + 10 = x(1.0003)
The initial amount will not be 0
x/x + 10/x = x(1.0003) / x
1 + 10/x = 1.0003
10/x = 0.0003
x = $33,333.33
You would need to deposit over $30,000
Answer:
Dharma and Jorge should purchase a group plan.
They could save $9.55
Step-by-step explanation:
A group plan will cost an average of $135.95 per month.
An individual plan will cost an average of $72.75 per month.
Two individual plans will cost an average of
per month.
Since $145.50 > $135.95, Dharma and Jorge should purchase a group plan.
They could save

Answer:
Chicken is $8
Duck is $5
Step-by-step explanation:
Step 1: Let represent the cost of chickens and let represent the cost ducks. Since we have two unknowns, we need two equations to find them.
Step 2: The total cost of chickens Michael sold last month can be shown as , and the total cost of ducks he sold last month can beshown as Since these together add up to 550, we get these equations:
We are also given that this month, Michael sold 44 chickens, and 36start text, 36 ducks, $532. This equaion can be expressed as:
Now that we have a system of the two equations, we can now go ahead and solve the two equations.
Step 3: We can now solve the system of equations by using the elimination method. Manipulate the equations so one of the variables has the same coefficients but with opposite signs.
Now eliminate
When we solve the resulting equation, we obtain that . Then, we can substitute this into one of the original equations and solve for to obtain .
Step 4: Recall that denotes the cost of a chicken and denotes the cost of a duck. Therefore, a chicken costs $8, and a duck costs $5
