How much does the company need to pay for the fruit? ** For the fruits, the company needs to pay 3 * 2 = $<<3*2=6>>6 per batch.
How much does the company need to pay for the milk? ** 10 liters of milk is a cost of 10 * 1.5 = $<<10*1.5=15>>15 for the company.
How much does it cost the firm to produce one batch of yogurt? ** So in total one batch is a cost of 15 + 6 = $<<15+6=21>>21.
How much does it cost the firm to produce three batches of yogurt? ** So three batches of yogurt is a cost of 3 * 21 = $<<3*21=63>>63.
