Step-by-step explanation:
X+y=156
<span>0.05x+0.25y=21.6
-1/4*/ x+y=156
1/20x+1/4y=216/10
-1/4x-1/4y=156*-1/4=-39
</span>1/20x+1/4y=216/10
<span>+--------------------------
-4/20x=-17,4
x=87
</span>x+y=156
<span>
87+y=156 y=69

Answer:
16
Step-by-step explanation:
The total profit is $93
He made a $45 profit selling hats
The question says he only sold t-shirts and hats
Since we are solving for the amount of t-shirts sold we subtract $45 from $93 and get $48 dollars earned from t-shirts
He makes $3 per t-shirt
We divide the amount per t-shirt by the total t-shirt money earned
This looks like: 48/3
We get 16 as our answer
