Noah was selling spirit wear. bruin t-shirts cost $12 and bruin sweatpants cost $30. he sold 70 items and made $1200. how many of each item did he sell
( show steps)

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$
