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
