Answer 1

Explanation:

51.72 plus 97.33 is 149.02

Answer 2

I spent $14.5 on the garden

Explanation:

This problem can be solved by simply adding the individual costs of the items put in the garden

Cost of the barrier:

We can get the cost of the barrier by first of all determining the perimeter of land the barrier covers. We have a hint in the question given: "One bag of mulch covers 8 square feet "

We can assume the shape of the garden to be a square and the area to be 8 square feet.

The length of the garden will be =
`√(area)` because the garden is a square.

Length =
`√(8) =2√(2)`

perimeter =
`4 * 2√(2)=4√(2) feet`

The barrier costs $1.50 per foot. for
`4√(2)` feet, =$8.5

Cost of barrier = $8.50

Cost of Mulch

The cost of mulch = $ 6

Total sum of money spent = 8.5 +6 = $14.5

Therefore, I spent $14.5 on the garden
