Question

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
(Please show steps)

Answer 1

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
