Task i
john has decided to fix up an old field for his son's horse. the length of the field is
10 meters less than 4 times its width. first, he fenced in the field at a cost of $4.80
per meter. the total cost was $1,584. he now needs to buy sweet grass seed to plant
in the field. the seed costs $3.98 per bag and covers 460 square meters.
how much money will john have invested in this field?

The total money invested in the field will be

Step-by-step explanation:

step 1

Find the dimensions of the field

Let

x -----> the length of the field

y -----> the width of the field

we know that

The perimeter of the field is equal to

so

----> equation A

------> equation B

substitute equation B in equation A and solve for y

Find the value of x

therefore

The length of the field is 130 meters and the width of the field is 35 meters

step 2

Find the area of the field

The area of the field is

substitute

step 3

Find the number of bags of seed

Divide the area by 460

Round up to the nearest whole number

step 4

Find the cost of the seed

step 5

Find the total money invested in the field
