Paul was asked to use the elmination to find the solution to the system of linear equations 5x + 4y = 1 −2x − 8y = −26 what are the missing steps in his work below? 5x + 4y = 1 −2x − 8y = −26 10x + 8y = 2 + (−2x −8y = −26) 8x + 0y = −24 8x = −24 x = −3 5x + 4y = 1 5(−3) + 4y = 1 −15 + 4y = 1 4y = 16 y = 4 select one: a. 5x + 4y = 1 + (−2x − 8y = −26) b. 2⋅[5x + 4y = 1] 10x + 8y = 2 c. 5x + 4y = 1 − (−2x − 8y = −26) d. −5⋅[−2x − 8y = −26] 10x + 40y = 130

Hank itzek manufactures and sells homemade wine, and he wants to develop a standard cost per gallon. the following are required for production of a 70-gallon batch. 2,700 ounces of grape concentrate at $0.04 per ounce 77 pounds of granulated sugar at $0.43 per pound 133 lemons at $0.79 each 350 yeast tablets at $0.24 each 350 nutrient tablets at $0.14 each 2,500 ounces of water at $0.001 per ounce hank estimates that 4% of the grape concentrate is wasted, 9% of the sugar is lost, and 32% of the lemons cannot be used. compute the standard cost of the ingredients for one gallon of wine. (round intermediate calculations and final answer to 2 decimal places, e.g.
