n200080 [17]

Global trade provides consumers with MORE OPTION AND LOWER PRICES.

Explanation:

Global trade provides consumers the opportunity to be exposed to goods and services not available in their home countries. Products that are sold within an international trading market are considered exports, while those purchased from the global trade market are labeled as imports.

Feliz [49]

Answer:

56.67%

Explanation:

Purchase cost = 30 dollars

Margin x price = 0.60x30 = $18

30-18 = $12

Profit = $47 - $30 - 0.07(12)

= 16.16

Percentage earned = (16.16 /18) * 100

= 89.78%

Profit from the trade

= 47-30

= 17

Percentage earned = 17/30 * 100

= 56.67%

The return would have been 56 67% if the investor had not done this.
