Let the cost of a shirt be s and a trouser be t.
trousers be t.
15s + 8t = 11 250 ................ (i)
Jack bought
$\frac{80}{100}$ x 15 = 12 shorts
$\frac{125}{100}$ x 8 = 10 trousers
12s + 10t = 11 700
Multiply eqn. (i) by 10 and eqn. (ii) by 8
150s + 80t = 112 500
196s + 80t = 93 600 -
54s = 18 900
s = 350
The cost of a shirt is sh 350
