Question

Derek owns a landscape business. He charges a fixed fee of $30 plus $1 per 1,000 square feet of lawn mowed. Derek's earnings (in dollars) in the past five weeks are {204, 344, 450, 482, 504}. To find the corresponding square footage of lawn mowed, construct a function that models the total area of lawn that Derek mows based on his earnings.

Answer 1

earnings = fixed fee + (amount per 1,000 square feet) * x

where x represents the number of 1,000 square foot areas being mowed

for each earnings value in the list, plug it into the earnings and solve for x
