Skylar earned a total of $84,000 last year, evenly split over the 12 months. For each month, Skylar spent 20% on her mortgage. Of the remaining money, she put ⅔ into her savings account. She put aside $1,200 for shopping. How much will Skylar have left over each month?

To solve this problem, let's break it down step by step.

### Step 1: Calculate Skylar's monthly income.
Skylar earned a total of $84,000 in a year, evenly split over 12 months.

\[
\text{Monthly income} = \frac{84,000}{12} = 7,000 \text{ dollars per month.}
\]

### Step 2: Calculate how much Skylar spends on her mortgage.
Skylar spends 20% of her monthly income on her mortgage. So, we need to find 20% of $7,000.

\[
\text{Mortgage payment} = 0.20 \times 7,000 = 1,400 \text{ dollars per month.}
\]

### Step 3: Calculate the remaining money after the mortgage.
After paying the mortgage, Skylar is left with:

\[
\text{Remaining money} = 7,000 - 1,400 = 5,600 \text{ dollars per month.}
\]

### Step 4: Calculate how much Skylar puts into her savings.
Out of the remaining money ($5,600), Skylar puts ⅔ into her savings. So, we need to find ⅔ of $5,600.

\[
\text{Savings} = \frac{2}{3} \times 5,600 = 3,733.33 \text{ dollars per month.}
\]

### Step 5: Subtract the amount she puts aside for shopping.
After setting aside $1,200 for shopping, the remaining amount is:

\[
\text{Remaining money} = 5,600 - 3,733.33 - 1,200 = 666.67 \text{ dollars per month.}
\]

### Final Answer:
Skylar will have **$666.67** left over each month.
