1. You are planting 750 acres in corn. You are applying 2 pints per acre of a burndown herbicide that costs $71.10 per 2 gallon container using a 30-foot sprayer. You are planting 28,000 kernels of corn per acre of an 80,000 kernel bag that costs $110 per bag using a 12-row, 30-in row planter. You are able to travel 4.5 mph with both your sprayer and planter. Allow an extra 15% of the total time for turning and filling. a.) How many days does it take to apply the herbicide and plant the corn, working 14-hour days? Click here to enter text. b.) What does the herbicide cost? (Note: you must buy a whole container.) Click here to enter text. c.) What does the seed corn cost? (Note: you must buy a whole bag.) Click here to enter text. d.)

Answer 1

1 = total time t = required for spraying - I 750x 627 2640 x 1 30x 12 4.5(63360) tet, Total area of field = 750 arres Total volume of Herbicide required = 75042 - 1500 pints = 187.5 gallom Total number of Kennels= (750x (28000) = 21,000,000 fetat bag length of planter - 30 inch x 12 - 360 inch (a) Total time required - t (let) for planting tatt ta (750X6272640 x 360 (48/63360) Speed - 4.5mph = 4.5 X 63360 inches / hown t = 45.833. lon ity = 0,15 xt, i t-titte = 1815x 45, 8333 t = 52.7083 hores - No of days = 3. 1648 days 360 (5) Tot; Total time required = t + t = 27, - 2 (52.7083) - 105.4166 hoss. Total days required = 105.4166 14 = 7.5297 days - 7.53 days x 8 days i whole i Ambn 20) I herbicide = /187.5 x 71.16. 2.5 L $ 5332.5 ③ Cost of corn need = 21,000,000 x 110 80,000 - $ 28,875 @ Germination - 26500 = 1.2619 x 10 21 000 000 0.12619 %
