Question

A coffee shop sells regular coffee in three sizes. The table shows the sizes of each regular coffee sold throughout the day. Write and solve a system of equations to determine the price of each regular coffee.
a) bajo: $1.60; mediano: $1.82; grande: $2.00

b) bajo: $1.61; mediano: $1.77; grande: $2.03

c) bajo: $1.62; mediano: $1.80; grande: $2.03

d) bajo: $1.65; mediano: $1.79; grande: $2.07

Answer 1

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
