An Inventory of two categories of computers showed a total of 60 computers with a total value of $2000. If computer A cost $25 each and computer B cost $50 each, how many of each computer was in inventory?

Solution

Solution;

let x be computer A

and y be computer B

Given totall computers=60

In equation form ,x+y=60 -----(1)

and also

total value of $2000

25x+50y=2000 -----2

solve 1 and 2 to get x and y values

multiply 1 with 25 and subtract from (2)

25x+50y-25x-25y=2000-1500

25y=500

y=20

when y is 20 substitte in (1) to get x

20+x=60

x=60-20=40

so40($25)+20($50)=$2000

there were 40 computers of A type

and there were 20 computer B type.
