Answer:
106 = 34 +4t
18 t shirts
Step-by-step explanation:
total profit = profit from hats + profit from tshirts
profit from hats = 34
profit from tshirts = 4* t where t is the number of tshirts sold
total profit = 34 + 4t
The total profit was 106
106 = 34 +4t
Subtract 34 from each side
106-34 = 34-34 +4t
72 = 4t
Divide each side by 4
72/4 = 4t/4
18 = t
He sold 18 t shirts
