Answer:
1547 km
Step-by-step explanation:
1547 km remain due to consistent decrease in the rate of 3400 km. As stated 6.5% decreases each year, and you are wanting to see the amount left after 7 years. So I said 0.065 x 7 = 0.455 (Because you want to move the decimal two places to the right in this case when plugging in the percentage into an equation.) So, now since I'm left with0.455 for the 7 years I simply multiplied that by 3400 km to get my answer. Which gave me the value 1547 km.
