For Daniel, these costs can be described by the equation y = 7x + 55 where y is total cost in thousands of dollars and x is the number of tons of coffee beans roasted.
For Elizabeth, these costs are given in the graph below.

Daniel : 
y = 7x + 55
so if he roasted no beans...x would be 0
y = 7(0) + 55
y = 55 thousand......spent on the coffee machine

Elizabeth :
notice how ur graph has points (0,60)...this is saying that when 0 beans were roasted, she paid 60 thousand for the coffee machine

therefore, Daniel paid the least for the coffee machine
