Answer:
y = 4/3
Step-by-step explanation:
The two equations can be added to eliminate x:
(0.1x +0.5y) + (-0.1x -0.2y) + (1.2) +(-0.8)
0.3y = 0.4 . . . . . simplify
Divide by the coefficient of y to find y:
y = 0.4/0.3
y = 4/3

Let
c-----------> represent the cost of each shirt without discount
t-----------> <span>total cost for the three shirts after the discount
d----------> discount
we know that
d=3c*0.20
t=3c-d-------------> 3c-[3c*0.20]--------> 3c*[1-0.20]=3c*(0.80)
the answer is 3c*(0.80)</span>
