Systems of Equations and Applications (graded)1. Solve the following system of equations.3x + 4y = 42x + y = 62. Solve the following system of equations.2x – 3y = 135x + 2y = 43. The Kraft Co. manufactures computer chips at a variable cost of $4 per chip and sells them for $10 each. If the fixed cost is $12,000 per month, what is the number of chips they would need to produce at the break-even point?4. The Sunshine Bakery sells pies at a fixed price of p dollars per pie. The total number of pies demanded daily, D, is related to the price, p, in dollars by the equation:D = -10p + 200On the other hand, the daily supply of pies, S, is related to the price, p, per pie by the equation:S = 15p – 50Determine the equilibrium price of pies; that is, the price at which the supply, S, and demand, D, are equal.
