producing a musical costs 88,00 plus 5900 per performance.one sold-out performance earns 7500 in revenue.if every performance sell out how many performances are needed to break even? you split 1500 between two savings accounts. account A pays annual 5% interest and Account B pays 4% annual interest.after one year,you have earned a total of 69.50 in interest how much money did you invest in each account? A metalworker has a metal alloy that is 20% copper and another alloy that is 60%copper.How many kilograms of each alloy should the metalworker combine to create 80kg of a 52% copper ?
@EclipsedStar
pls help me
1. 88000/1600=55. So, it will break even in 55 performances.
2. check 0.05(950) + 0.04(550) = ? = 69.50 checks.
3. For this question, I used applications of linear systems. Mass of 20% alloy needed is 16kg. Mass of 60% alloy needed is 64kg.
The work for question 3 is a lot....so I omitted it XD
