Answer:
$718
Step-by-step explanation:
If Johan keeps doing his own landscaping, his contribution to the GDP will include:
- $210 spent on mulch
- $216 spent on flowers and plants
- $46 spent on fertilizer
- $246 spent on gasoline and lawn mower maintenance services
total contribution to the GDP = $210 + $216 + $46 + $246 = $718
All the items that Johan purchases are final goods, but his labor does not add to the GDP because he doesn't sell it to anyone else, he does the garden for his own personal benefit.
