The unit cost of the fencing and the cost of a bag of mulch together with
the area and perimeter of the garden give a cost sum of $36.5.
Response:
- The amount required to spend is <u>$36.5</u>
Cost of the barrier per feet (unit cost) = $0.75
Area covered by one bag of mulch = 7 square feet
Cost of one bag of mulch (unit cost) = $5
From the given diagram, we have;
Area of the garden = 8 ft. × 2 ft. + 0.5 × 8 ft. × 3 ft. = 28 ft.²
Length of fencing = 2 ft. + 8 ft. + 2 ft. + 5 ft. 5 ft. = 22 ft.
- Amount to spend = 4 bags × $5 + 22 ft. × $0.75 =<u> $36.5</u>

Answer:
- 40 packages from Fred Motors
- 20 packages from Admiral Motors
- 40 packages from Chrysalis
Step-by-step explanation:
I would formulate the problem like this. Let f, a, c represent the numbers of packages bought from Fred Motors, Admiral Motors, and Chrysalis, respectively. Then the function to minimize (in thousands) is …
objective = 500f +400a +300c
The constraints on the numbers of cars purchased are …
5f +5a +10c >= 700
5f +10a +5c >= 600
10f +5a +5c >= 700
Along with the usual f >=0, a>=0, c>=0. Of course, we want all these variables to be integers.
Any number of solvers are available in the Internet for systems like this. Shown in the attachments are the input and output of one of them.
The optimal purchase appears to be …
- 40 packages from Fred Motors
- 20 packages from Admiral Motors
- 40 packages from Chrysalis
The total cost of these is $40 million.
