Question

Tanya buys 4 pens and 6 markers. A pen cost p dollars each and markers cost 2 dollars more than a pen. Consider the expression: 4 p + 6(p + 2) What does 6(p + 2) represent?

Answer 1

6 (p+2) represents the cost of 6 markers. As markers costs 2 dollars more than the pen, p+2 represents the cost of a marker and 6 markers would be 6(p+2). Similarly, 4p represents the cost of 4 pens.
