Drew invested $20,000 in a company that manufactures toy cars. It costs Drew $1.50 to manufacture each toy car, which he will then sell for $4.00. The system graphed below can be used to determine the break-even point, where expenses equal income. The variable y represents both the dollar amount of the expenses as well as the dollar amount of the income.

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
