Answer:
1%
Step-by-step explanation:
We use the simple interest equation of A=P(1+rt).
A-the total amount with interest earned
P-the initial amount or principal
r-rate
t-time in years
We substitute the values P=6900, A=6923, and t=0.33 since 4 months divided by 12 months is 0.333 years. We then solve for r.

Our final step is to divide both sides by 0.33.

This is the decimal of the rate. We convert to a percentage by multiplying by 100. 0.01(100)=1%.
Answer:
The solution is given in attached diagram:
Answer: x = -1 y = 4 I got my answer by solving for one variable in the first equation and then substituting what I got for that variable into the second equation in place of that aforementioned variable then solving for the last variable.
The break-even point for the graph is at 11 units.
Step-by-step explanation:
Break-even point refers to the point on the graph where either of the parameters of the graph intercepts each other. The corresponding location of the position where the intersection occurs gives the break-even point.
In the graph annual cost is plotted in green on the Y axis, while the sales are plotted on x-axis in red.
When we observe the graph carefully, we find that two-line intercepts. When the point at which interception occurs is extended on the x-axis, the point is 11 units, which gives us the break-even units.
Hence the point is 11 units.
