A computing center normally spends $1600 per month for tapes and 3/5 of this for Heavy Duty Tapes. How much will they save per month under the new prices?Explanation / Answer
1) let one machine takes x minutes
and other machine takes y minutes
x + y = 85
x = 3/2 y
3/2 y + y = 85
5/2 y = 85
y = 34
x = 85 - 34
x = 51
hence, machine doing the longer job took 51 minutes
