Atomato grower needs to ship early when prices are high and spoilage is low. she now has 25 tons on hand and by can add two tons a week by waiting. the current profit is $250 per ton but it will reduce $15 per ton for each week she delays. when should she ship to receive the maximum profit?

On first week

Quantity of tomato = 25 tons

profit per ton = $250

So if she sells tomato on first week then total profit = 25 * 250 = $6250

On second week

Quantity of tomato =27 ton

profit per kg =$ 235

So if she sells tomato on second week then total profit =27* 235= $6345

On third week

Quantity of tomato = 29 ton

Profit per kg = $220

So if she sells tomato on third week then total profit = 29*220 = $6380

Now consider fourth week

Quantity of tomato =31 ton

Price per kg = $205

So if she sells tomato on fourth week then total profit =31*205 = $6355

so she must ship her tomatoes on third week i.e she will attain $ 6380 as profit.
