Bobby · Answer 1

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
