Answer 1

Answer:

$105+25n$

where $n$ is the number of weeks

Step-by-step explanation:

Initial money available with Tom = $105

Allowance given to Tom every week = $25

To find:

Equation for money available with Tom given a number of weeks.

Money available with Tom after first week = $105+ $25 = $130

Money available with Tom after second week = $130+ $25 = $155 OR 105+ 2 $\times$ 25

Money available with Tom after third week = $155 + $25 = $180 OR 105+ 3 $\times$ 25

and so on.

Money available with Tom after $n$ weeks = $105 + $25 $\times n$

Therefore, the equation is:

$105+25n$
