White chocolate costs $4.00 per bar, and dark chocolate costs $5.00 per bar. You buy 15 bars of chocolate for $68 dollars

A) Write the system of equations.
B) How many solutions does this system of equations have?
C) Describe the system of equations graphically by identifying the type
of lines that match the solutions of this system of equations.
D) Explain your solution in terms of chocolate bars.

(A, B,C, D are the steps i had to do to complete this question)

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

step-by-step explanation:

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.

step-by-step explanation:

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)
