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
Let be the smallest of the consecutive integers summing to 2020. Then the largest integer in the sum is so our answer is
For completeness, though, let's solve for the value of that satisfies the conditions of the problem. Recall that the sum of an arithmetic series with first term last term and terms, is Plugging in our known values gives us the equation which simplifies to Thus, so the 4040 consecutive integers are Notice how everything except the cancels out!
