Every lorry working for a haulage firm drives between 30,000 and 45,000 miles a year. The company fits a statistical model to relay the miles travelled by each of its Lorries last year to the revenue earned by each. They acquired the relationship where R is revenue (GH¢1000) and m is miles (1000s).

a) How much revenue would you guess a lorry doing 40,000 miles in a year to earn?

b) How many miles a year should a lorry drive to earn revenue of GH¢35,000 a year
