In order to see if James is
correct or not with his solution to the problem,
you need to make sure that you understand the
problem yourself. In this problem, James and three of his
friends are going to a basketball game where it
costs $3 for each to get in. He wants to figure
out the total cost of the four of them to go to
the game.
Before worrying about if James is correct or
not,
you want to go through the steps of solving this
problem and then compare your solution with James'.
There are a couple of ways to solve this problem.
The strategy you use will be to choose an operation.
You could either add $3 four times for each of
the boys or you can multiply the $3 by the four
boys. Hopefully you chose to multiply $3 by the
four boys.
Simply, you know that to solve this problem you
would multiply $3 times the 4 boys to find that
it will cost $12.
Now, look over James' work. You will notice two
things incorrect with his solution compared with
the way you solved it. First, he added 4 boys instead
of multiplying and his final answer of $7 is incorrect
compared to your answer of $12.
Look over your choices, A through D, and see which
one best represents the correct way to solve this
problem.
After reading over the four choices, you realize
that letter D best shows what James should have
done in order to come up with the correct answer. The answer is letter D. |
