You put a barrier around the garden and cover it with a layer of mulch. The barrier costs $1.25 per foot. One bag of mulch covers 10 square feet and costs $3.00. How much do you spend?
To answer this question, we need to know the size of the garden. Let's assume the garden is a rectangle with a width of 10 feet and a length of 20 feet.
Perimeter of the garden: 2(10) + 2(20) = 60 feet
Cost of the barrier: 60 feet x $1.25/foot = $75
Area of the garden: 10 feet x 20 feet = 200 square feet
Number of bags of mulch needed: 200 square feet รท 10 square feet/bag = 20 bags
Cost of the mulch: 20 bags x $3.00/bag = $60
Total cost: $75 + $60 = $135
Therefore, you would spend $135 to put a barrier around the garden and cover it with a layer of mulch.
