How many strings does Dave break in a week? ** He breaks 2 strings a night for 6 nights for a total of 2*6 = <<2*6=12>>12 broken strings
How many guitar strings will Dave need to replace? ** He breaks 12 strings per week so over 12 weeks, he will need to replace 12*12 = <<12*12=144>>144 guitar strings
