Answer:
The original price of the car can be written in percentage which is 100%. Because the price increased by 6%, therefore, the new price should be represented as:
100% + 6% = 106% = 1.06 (remember: not 0.06, that is how much the price increased, not 0.94 either, because the price increased, not decreased).
So the answer for the first question should be:
(a) new price = 1.06 × original price
from that, we can appy the answer above for the second question:
(b) new price: $33390
