Question

Jack has $205 and he is spending $2 each day. Which algebraic expression describes this situation, where d represents the number of days?

Answer 1

M= 205 - 2d

1) We can write a mathematical sentence for that situation, considering Jack's initial amount of money: $205 and the fact that we don't know the number of days (d). But we do know that each day costs Jack $2, i.e. minus 2 dollars per day.

2) Therefore, we can write out the following:

`M_{}=205-2d`

Where M stands for Jack's money and "d" stands for the number of days.

3) Hence the answer is

M= 205 - 2d
