Each week, Robbie earns $x mowing lawns and receives $15 as his allowance. To find how much he will earn in total over 3 weeks, Robbie calculates : x+15+x+15+x+15.What is another way Robbie can calculate how much he will earn in total over the 3 weeks? Drag and drop the equivalent expression in the box.

Answer 1

Since there are three variables and three constants you add like terms.

3(x+15) = 3x + 40

Answer 2

3(x+15) is the answer I just took the quiz.
