This is because a new hire messed everything up and sold everything at a different cost. If the total amount made from small drinks is $155.25 and the amount made from medium drinks is $397.80. Write a matrix-vector equation to represent the scenario and find out how much the new hire sold small and medium drinks for. (2 pts for equation, 3 pts for solving)

Complete Question: The complete question is in the file attached to this solution

a)

b) The new hire sold a small drink for $1.78 and a medium drink for $3.13

Step-by-step explanation:

The matrix vector equation can be written as:

............(1)

let X₁ = Price of small drinks

Let X₂ = Price of medium drinks

The vector of  the prices of small and medium drinks is:

The matrix of the total sales can be written as:

According to the equation written in  (1), the matrix vector equation is:

Solving for X₁ and X₂ in the equations above:

X₁ = 1.78

X₂ = 3.13
