Explanation:
You didn't say what you want us to help you with and I couldn't find the exact question online. But based on your question, it seems you want to calculate the total cost of the packages sold. This will be:
For three months, she sold one $3,500 package and one $2,550 package each month. The total sold for the three months will then be:
= 3($3500 + $2550)
= 3($6050) = $18150
We then add the value gotten to what was sold in the fourth month. This will then be:
= $18150 + $4,250
= $22400
