Question

After buying a package of screws and building some desks, Donald has 75 acres left. Approximately how many more desks can he build? (Show work)

Answer 1

The provided question about Donald's screws is incomplete and cannot be solved, but similar problems involving calculations of resources can be solved using algebraic approaches, such as determining mowing acres or the number of laser printers needed for an office.

Step-by-step explanation:

The question how many more desks can Donald build with 75 screws does not provide enough information for a specific answer. However, we can show how to solve similar problems that provide more data, like mowing acres or determining the number of laser printers needed.

For example, using the equation ŷ = 1350 - 1.2x, where ŷ represents the acres left to mow and x is the number of hours of work:

1. To find the acres left to mow after 20 hours, substitute x = 20 into the equation, yielding ŷ = 1350 - 1.2(20), which calculates to ŷ = 1350 - 24, thus ŷ = 1326 acres.
2. After 100 hours of work, substituting x = 100 gives ŷ = 1350 - 1.2(100), resulting in ŷ = 1350 - 120, so ŷ = 1230 acres.
3. To find when all the lawns will be mowed or when ŷ = 0, we set ŷ = 1350 - 1.2x to 0 and solve for x, which would be x = 1350 / 1.2, giving the total hours required to mow all the acres.

Such calculations are essential in various fields, whether for landscaping company needs or outfitting office buildings.
