1. the school band sells carnations on valentine's day for $2 each. they buy the carnations from a florist for $0.50 each, plus a $16 delivery charge.
a. write a system of equations to describe the situation.
a: y = 2x; y = 0.50x + 16. b. graph the system. what does the solution represent?
(which x-values should i choose to graph the equations above so that they intersect? )
c. explain whether the solution shown on the graph makes sense in this situation. if not, give a reasonable solution.
2. 6(x + 2) = -2(x + 10) can you explain how you solved this equation for the answer to be -4?

A;) The equations are already given. y = 2x depicts the revenue of the school, whilce y = 0.50x + 16 depicts the total cost of buying the carnations.

b.) The graph is shown in the attached figure. The orange line is for the cost, while the blue line is for the revenue. Basing on the graph, they would intersect at an estimate of x = 11 carnations.

c.) The graph makes sense  At fewer carnations, the cost is greater than the revenue. When the two lines intersect, that means that it has reached its breakeven point. This is the point where you have caught up with the cost. After the breakeven point, your profit will always be greater than your initial cost.

d) 

6(x+2) = -2(x+10)
6x + 12 = -2x -20
6x + 2x = -20 - 12
8x = -32
x = -4

What is the last question i don’t see it?
