At an electronics store, DVDs are on sale. Some DVDs cost $15.00 each and some cost $12.00 each. Bart purchased 8 DVDs and spent a total of $105.00. Write a system of equations and solve by using substitution to determine how many $12.00 DVDs Bart purchased.

$105

15*3=45

12*5=60

60+45=105

(12*5)+(15*3)=105

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

d is the correct answer

step-by-step explanation:
