Eli had $10, but he lost some of it. his mom doubled the money he had left. eli wrote the expression 2(10 – k) to show how much money he has now, where k is the amount of money he lost. aisha wrote another correct expression, 20 – 2k, to also show how much money eli has now.

Both the equations would work

Step-by-step explanation:

If you want to see if both the equations would work, just try plugging in numbers. If you plug in 5, the first equation would give you 10 and the second equation would give you 10 too. This would be the same for every number. This shows that they were both right and both the equations are the same. All Aisha did was distribute the 2 onto both variables in the parenthesis.

one set of data has more variation than the other. hope this !
