Each year, Johan typically does all his own landscaping and yard work. He spends $205 per year on mulch for his flower beds, $229 per year on flowers and plants, $58 on fertilizer for his lawn, and $250 on gasoline and lawn mower maintenance. The lawn and garden store where he obtains his mulch and fertilizer charges other customers $501 for the service of spreading that much mulch in flower beds and $51 for the service of distributing fertilizer over a yard the size of Johan's. Paying a professional yard care service to mow his lawn would require an expenditure of $1 comma 174 per year, but in that case Johan would not have to buy gasoline or maintain his own lawn mower.

a. In a normal year, calculate by how much does Johan's landscaping and yard work contribute to GDP.$

b. Suppose that Johan has developed allergy problems this year and will have to reduce the amount of his yard work. He can wear a mask while running his lawn mower, so he will keep mowing hisyard, but he will pay the lawn and garden center to spread mulch and distribute fertilizer. How much will all the work on Johan's yard contribute to GDP this year?
