Answer: 14.02%

Explanation:

Prices = ¥652,000

Exchange rates = ¥197/£

Change in exchange rate = ¥190/£

Original price of the Toyota tundra

= ¥652,000/197

= £3009.65.

Change in price

= ¥652,000/190

= £3431.58.

Percentage change in price of the imported trucks

= ( New price - Old price) / old price x 100

= £3431.58 - £3009.65 / £3009.65 X 100

= 421.93 / £3009.65 x 100

= 0.1402 x 100

= 14.02%
