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.
Based on Derek's earnings, the corresponding square footage of the lawns he mowed in the past five weeks is...
(174, 314, 420, 452, 474)
(203.97, 343.97, 449.97, 481.97, 503.97)
(234, 374, 480, 512, 534)
(174,000, 314,000, 420,000, 452,000, 474,000)
