Answer:
c) bajo: $1.62; mediano: $1.80; grande: $2.03
Step-by-step explanation:
Insert numbers from the table into a linear equation (ignore time column) and use Cramer's Rule.
55x+53y+54z=299.12
17x+22y+25z=117.89
30x+23y+29z=148.97
x, bajo = 1.62
y, mediano = 1.8
z, grande = 2.03
 
        
             
        
        
        
1 hour and 7 1/2 minutes per picture 
2 1/4 = 60 * 2 = 120 + 15 = 135/2= 67.5 = 1 hour and 7 1/2 minutes
