To find the rate of commission, we need to calculate how much commission she earned based on her sales and then divide it by the total sales.

The sales representative earned $1484.40 for the month, which includes both her salary and commission. Her salary is $1314, so the remaining amount is her commission.

Commission = Total earning - Salary
Commission = $1484.40 - $1314
Commission = $170.40

Now, we can calculate the rate of commission by dividing the commission by the total sales.

Rate of Commission = Commission / Total sales
Rate of Commission = $170.40 / $5680
Rate of Commission ≈ 0.03 or 3%

Therefore, the sales representative's rate of commission is approximately 3%.
