Explanation / Answer

Given, cost for him on three times,

let shirts be x, slackspair be y, sports coats be z

so,

1st time equation of total cost will be :

4x+2y = $20.94...........(1)

2nd time equation of total cost will be:

5x+2y+2z = $38.91...........(2)

3rd time equation of total cost will be:

3x+2z = $23.95...........(3)

(2) - (1) , substracting 1 from 2 will give,

x+2z = $17.97..........(4)

for equation (4) multiply with 3 ,

we will get , 3x+6z = $53.91..... (4a)

substract (4a) and (3) , we will get

4z = $ 29.96 implies,

z = 7.49

from this, x = 2.99

from x, we can get y from equation1 as

y = 4.49

as our answers.
