Katen [24]

First you'd subtract .58 from 2.23 to get the price of the notebook.

2.23 - .58 = 1.65

(2.23×2)+1.65= 6.11

Now subtract 6.11 from ten to figure out the change amount.

10 - 6.11 = 3.89

$y=64.96+25.41x\\y=64.96+25.41*3\\y=141.19$

The residual is:

$R=200 - 141.19\\R=58.81$

The answer is alternative A.58.81
