Answer:
The systems of equation are identical and such there are infinitely many solutions. For the first part the correct answer is B. For the second part, the correct answer is A
Step-by-step explanation:
If we multiply the first equation by 4 the result is the second equation and thus the systems of equations are scalar multiples of each other. The solution to such a system is found by expressing one variable in terms of the other hence choice B.
Since the systems are scalar multiples of each other, if we graph them they would simply coincide since they are identical, that is they have same slope and y-intercept.

Answer:
Revenue = $452.2
Step-by-step explanation:
Given,
The selling price of a calculator, P = $16.15
The given equation is R = 16.15*q
We know that, Revenue = Price*Quantity
If the selling numbers of calculators is 28,
according to the question,
Revenue = $16.15*28
Revenue = $452.2
That is an example of a linear equation. In this equation, if we increase the quantity sold, the revenue will increase automatically.
