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 
25
Money available with Tom after third week = $155 + $25 = $180 OR 105+ 3 25
and so on.
Money available with Tom after weeks = $105 + $25 
Therefore, the equation is:

Step-by-step explanation:
Total volume of sand = pi/3*(6^2)*(15) + pi*(6)^2*(30) = 1260*pi mm^3
So it will therefore take 1260*pi/10*pi = 126 seconds for all of the sand from the top hourglass to drip down to the bottom hourglass.
