Answer 1

Jose received $30 for his birthday and put it in his piggy bank. Each week, he puts 4 more dollars in his bank. The amount of money in dollars D in his bank is given by D = 4w + 30 where w is the number of weeks he has saved 4 dollars. His sister Marisol makes a table of reasonable values for w. Marisol selects 16 as a value for w.

What is the corresponding table entry for D?

A.
34

B.
434

C.
50

D.
94

Answer 2

Ok D = 4w + 30 is the formula for working out the amount of money in the bank after w weeks
So you need to replace w in this formula by 16 and calculate D.

Can you try this?
