Adam and Betty purchased a printer together for $258. If Adam paid $18 less than twice of what Betty paid, how much money did Adam pay for the printer?
Correct answer: B. 166
- A. 172
- B. 166
- C. 158
- D. 146
Explanation
To solve this problem, set up two equations based on the given information: Adam's payment as x and Betty's payment as y. The equations are x + y = 258 and x = 2y - 18. By solving these equations simultaneously, it is found that Adam pays $166 for the printer. The incorrect options resulted from miscalculations or misinterpretation of the equations.
