1)Mr.Chan deposits $20000 into Bank A at a rete of of5% and $30000into bank B at a rate of 6%. Two banks are in system of simplee interest. How much will he have 3 years later? The amount he will have =(20000x5%x3+20000)+(30000x6%x3+30000) =$58400 2)If two internal angles of a triangle is 58o and 47o, what is the remaining angle? ∠ sum of ?=180o ∴The remaining angle =180o-58o-47o =75o
