Answer:
1. 8/$12=21/$x then cross multiply. 
2. 1/$1.5, we're looking for cost so $1 is more reasonable 
3. $31.5
Step-by-step explanation:
12x 21/ 8 = 31.5 
 
        
                    
             
        
        
        
Answer:
m∠QTR = 98°
Step-by-step explanation:
From the picture attached,
Radii of the circle are TQ and TR measuring equal lengths.
Therefore, ΔTQR is a isosceles triangle.
Opposite angles of the equal sides will be equal in measure.
m∠RQT = m∠TRQ = 41°
By angle sum theorem,
m∠RQT + m∠TRQ + m∠QTR = 180°
41° + 41° + m∠QTR = 180°
m∠QTR = 180° - 82°
               = 98°
Therefore, m∠QTR = 98°
