Answer:

r(t) = 75 kg - (4.5 kg/wk)w

Step-by-step explanation:

Let r(t) represent the amount of rice remaining after w weeks.

Then:

r(t) = 75 kg - (4.5 kg/wk)w

Amount of remaining rice = r = 75 - 4.5w

Given that;

Total amount of rice = 75 kg

Rice use in each week = 4.5

Find:

Equation for remaining week

Computation:

Assume;

Number of week = w

Amount of remaining rice = r

So.

Amount of remaining rice = Total amount of rice - (Rice use in each week)(Number of week)

r = 75 - (4.5)(w)

r = 75 - 4.5w
