He buys 5 pounds of eggplants and 4 pounds of zucchini so he buys 5+4 = <<5+4=9>>9 pounds of produce
These 9 pounds are $2.00 a pound for a total of 9*2 = $<<9*2=18.00>>18.00
He needs 4 pounds of tomatoes that are $3.50 a pound for a total of 4*3.50 = $<<4*3.50=14.00>>14.00
He needs 3 pounds of onions that are $1.00 a pound so that's 3*1 = $<<3*1=3.00>>3.00
The basil is sold by the half-pound and he needs a full pound so that's 2.50*2 = $<<2.5*2=5.00>>5.00
The eggplants and zucchinis cost $18.00, the tomatoes are $14.00, the onions are $3.00 and the basil is $5.00 for a total of 18+14+3+5 = $<<18+14+3+5=40.00>>40.00
This recipe makes 4 quarts and the total price of the vegetables was $40.00 so each quart costs 40/4 = $10.00
