1. Joan spent Monday and Tuesday shopping. She spent a total of $115. She spent $47 more on Monday than she did on Tuesday. How much did she spend on Tuesday? a. $68 b. $162 c. $34 d. $81 e... . $115 Correct Answer: We are simply looking for 2 numbers that when added together, we get 115. Also, one number is 47 more than the other. Let x represent the smaller number, then x + 47 would be the larger, so we have the equation: x + x + 47 = 115 Combine the x with the other x gives: 2x + 47 = 115 Subtract 47 from both sides. 2x = 68 Divide each side by 2 gives: x = 34 2.
