Final answer:
Loyal Customer A is responsible for bringing in $2,015 in revenue to the business.
Step-by-step explanation:
Loyal Customer A is responsible for bringing in revenue by spending an average of $35 on movie rentals and purchases every weekend. They have been doing this for the last two years. Additionally, they referred a new customer to your video rental shop who has been spending $15 on movie rentals every two weeks for the past six months. To calculate the revenue Loyal Customer A is responsible for, we can add up their own spending and the spending of the customer they referred:
Loyal Customer A's spending: $35/week * 52 weeks/year = $1,820/year
Referral customer's spending: $15/2 weeks * 26 weeks/year = $195/year
Total revenue from Loyal Customer A: $1,820 + $195 = $2,015/year
