Fresh tomatoes cost $.95 per pound to grow from seed to harvest. If they are sold fresh, packaging costs $.35 per pound and 35% of the whole quantity goes to waste during handling. The farmer sells the fresh tomatoes to a wholesaler for $2.15 per pound. If they are sold dried, the drying/packaging process costs $.55 per fresh pound and the mass of tomatoes decreases through dehydration by 75%. What price per pound should the farmer sell the dry tomatoes for, in order to make the same percent profit as on the fresh tomatoes?

Product | Cost Fresh | Handling | Weight loss | Cost per lb | Sell per lb | Net Profit |

Fresh Tomato | .95 | .35 | 35% | 2.00 | 2.15 | 0.15 |

Dry Tomato | .95 | .55 | 75% | 6.00 | p | p-6.00 |

To find the final cost per lb, we proceed as follows:

After a weight loss of 35%, only 65% of the mass is left, therefore the cost per lb. can be found from the proportion:

For the dry tomatoes:

The net profit is not the same as the percent profit: a net profit of $.15 cents over a cost of $2.00 must be in the same ratio as a net profit of p-6.00 over a cost of $6.00:

The selling price for the dry tomatoes must be $6.45/lb.
