The function that best represents the data is y = 0.75x + 4.5. The slope in this case represents the increase in the amount she spends in $ due to the number of cards she makes. The intercept with the Y axis (4.5) means that she has an expense of 4.5 $ without having made any card yet.
75 percent is 12 which is 3/4 so make a proportion .75/12 = 1/x cross multiiply and you get 16
