Question

Amelie completed 56 sit-ups. This is 7 times the number of sit-ups that Kiki completed.

Let k represent the number of sit-ups Kiki completed. Which equations model this problem

Answer 1

k=8

Explanation:

If Amelie completed 56 sit-ups and its 7 times more you would divide

y=kx

k=56 divided by 7

k=8

k is the constant of proportionality

Answer 2

In the problem, we are told that Amelie completed 56 sit-ups, and this is 7 times the number of sit-ups that Kiki completed.

We can use this information to create an equation that models the problem.

Let k represent the number of sit-ups Kiki completed.

One equation that models this problem is:

k = 56/7

Another equation that models this problem is:

56 = 7k

Both equations represent the same information, the first one is solved for k, and the second one is solved for the number of sit-ups Amelie completed.

So either k = 56/7 or 56 = 7k is the equation that models the problem.
