³ Problem
A charity collected $3,600 to help support a local food kitchen.
$450 will be given to the food kitchen every month until the
funds run out. How many months will the charity support the
kitchen?
Reminder: If x = months and y = money left, then
y = 3600 - 450x.
The support of $450 per month will last for 8 months since
y(8) = 3600 - 450(8) = 0 as shown in the table of values.
