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

Seattle bank’s start-up division establishes new branch banks. each branch opens with three tellers. total teller cost per branch is $96,000 per year. the three tellers combined can process up to 90,000 customer transactions per year. if a branch does not attain a volume of at least 60,000 transactions during its first year of operations, it is closed. if the demand for services exceeds 90,000 transactions, an additional teller is hired and the branch is transferred from the start-up division to regular operations. required what is the relevant range of activity for new branch banks

Miller mfg. is analyzing a proposed project. the company expects to sell 14,300 units, plus or minus 3 percent. the expected variable cost per unit is $15 and the expected fixed cost is $35,000. the fixed and variable cost estimates are considered accurate within a plus or minus 3 percent range. the depreciation expense is $32,000. the tax rate is 34 percent. the sale price is estimated at $19 a unit, give or take 3 percent. what is the net income under the worst case scenario?

What is the difference between total utility and marginal utility? a. marginal utility is subject to the law of diminishing marginal utility while total utility is not. b. total utility represents the consumer optimum while marginal utility gives the total utility per dollar spent on the last unit. c. total utility is the total amount of satisfaction derived from consuming a certain amount of a good while marginal utility is the additional satisfaction gained from consuming an additional unit of the good. d. marginal utility represents the consumer optimum while total utility gives the total utility per dollar spent on the last unit.
