Using linear functions, it is found that:
- The system is:
[tex]y_G(x) = x + 30[/tex]
[tex]y_A(x) = 3x + 10[/tex]
- Using the graph to find the solutions of the system, we have that the total cost would be of $40 at both shops.
A linear function has the following format:
[tex]y = mx + b[/tex]
In which:
- m is the slope, which is the rate of change.
- b is the y-intercept, which is the fixed value.
At Greenpoint Florist, $1 is charged per rose, plus $30 for the vase, hence, the equation is:
[tex]y_G(x) = x + 30[/tex]
At Ashley's Flowers, $3 is charged per rose, plus $10 for the vase, hence, the equation is:
[tex]y_A(x) = 3x + 10[/tex]
At the end of this answer, the two solutions are graphed, and it is found that when 10 roses are sold, the total cost would be of $40 for at both shops.
