(Please show steps)
1 answer:
Answer:
Step-by-step explanation:let x be number of T-shirts and y be no of pants.
Total=70
I.e. x + y = 70 ..........1
Cost of one shirt=12$
Cost of one pant=$30
Total cost=12x +12y=1200$........2
1 +2
X+ y=70
12x+30y=1200
I.e. 12x + 12 y = 840
-(12x +30y)= -1200
.............................................
-18y = - 360
Y = 20
Therefore
No of shirts = x = 70 - y = 70-20=50$
No of pants =y=20$
Hope it is clear
