Andre received $60 for his birthday and put it in his piggy bank. Each week, he puts 3 more dollars in his bank. The amount of money in dollars D in his bank is given by D = 3w + 60 where w is the number of weeks he has saved 3 dollars. His sister Lana makes a table of reasonable values for w. Lana selects 42 as a value for w. What is the corresponding table entry for D?

(TEACHER HINT: They are asking what D will be if w is 42.)
