Please help! I am struggling

Eastern Motors Auto Dealership wanted to estimate the average CLV over a 5 year time horizon of a customer who purchases a new vehicle. The average vehicle sells for $24,000 and has a margin of 8%. Based on historical averages, 78% of people buying a new vehicle at Eastern will return for service 8 times over the next 5 years. Though it varies considerably, Eastern generates approximately $125 in margin on each service visit after accounting for parts and direct labor costs. What would be the value of a service loyalty program that increased the average number of visits by 2 (over 5 years) and increased the probability that a new vehicle purchaser would return for service by 5 percentage points (e.g. from 75% to 80% ) on a per customer basis? CALCULATED VARIABLES: tclv=$2,700clv=$780service=$1,000margin=$1,920
