Shannon sells handmade wallets for $12 each. Yesterday, she sold n wallets. Today, she sold 3 less wallets than yesterday. Over the past two days, she earned a total of $396. Drag and drop terms and an operation to create an equation that models the situation. Then, solve for n, the number of wallets Shannon sold yesterday. 15 12n + 3 + 396 396 3n n - 3 n - 3 n + 3 12n
Okay so what do you have so far
nothing really
Are you creating a system? or simply 1 equation?
1 equation
Alright, so we know that the total is 396, so that needs to go on the left side of your equation
ok
Which one would you think you would put in for "todays" profits?
Yesterdays is easier, so start with "yesterday"
n-3
She sold "n" wallets yesterday for $12 each
So Yesterday is really 12n
Scratch that, I just reread the question Your answer is: 396 - 12n = 3n You get this answer because we are solving for "Yesterday". You would need to subtract "Today" from the total. In addition, she sold 3 more wallets "Yesterday" so you would need to factor in that.
You would not have been able to do (n-3) because that would mean number of wallets minus $3
