Answer:
Option d. $22154 is the right answer.
Step-by-step explanation:
To solve this question we will use the formula
In this formula A = amount after time t
P = principal amount
r = rate of interest
n = number of times interest gets compounded in a year
t = time
Now Lou has principal amount on the starting of first year = 10000+5000 = $15000
So for one year
= $15900
After one year Lou added $5000 in this amount and we have to calculate the final amount he got
Now principal amount becomes $15900 + $ 5000 = $20900
Then putting the values again in the formula
So the final amount will be $22154.
The raised price represents 110% of the original price (100% plus the extra 10%)
A percentage is converted into a decimal multiplier by dividing by 100:
To clarify the final stage, consider this (where
is the original price):
From here, basic algebraic rules make solving for easy:
Therefore the original price of a ticket was $175
