During the day, Sam's Soda Shop took in $261. Also, Sam received a check in the mail for $173 as a refund for several bills that he had inadvertently paid twice. (a) Was Sam's net worth more or less at the end of the day? By how much? (b) What computation does part (a) illustrate? (c) If you think of the $173 check as removing or taking away the bills previously paid, what computation does this represent? Explain. (a) Sam's net worth was by S (b) Write the computation illustrated in part (a). ... = 434 (Do not include the $ symbol in your answer. Do not simplify.) (c) If you think of the $173 check as removing or taking away the bills previously paid, what computation does this represent? O A. 261+(-173)=88, because removing an amount represents addition and a bill represents a negative amount. OB. 261+173=434, because removing an amount represents addition and a bill represents a positive amount. OC. 261-173-88, because removing an amount represents subtraction and a bill represents a positive amount. OD. 261-(-173)=434, because removing an amount represents subtraction and a bill represents a negative amount. L
