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 12 as a value for w.

What is the corresponding table entry for D?

anonymous · Answer

well, try putting 12 as the value for w in that equation. I get

D = 3 x 12 + 60

D = 36 + 60

D = 96

do you agree?
