Question

Andre received $60 for his birthday and put it in his piggy bank. Each week, he put 3 more dollars in the 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?

A. 372
B. 96
C. 75
D. 64

Answer 1

Answer:

96 (dollars)

Step-by-step explanation:

D represents the amount of money Andre has in his bank after w weeks.  This formula is written as D(w) = 3w + 60 (dollars).

After 12 weeks, Andre will have accumulated D(12) = 3(12) + 60 dollars, or

36 + 60 dollars, or 96 dollars.  This is answer choice B.
