Answer:
1110
Step-by-step explanation:
Let x = price of the ticket before tax
We know the ticket plus the tax = 1232.10
x + x*11% = 1232.10
x+.11x = 1232.10
1.11x = 1232.10
Divide each side by 1.11
1.11x/1.11 = 1232.10/1.11
x=1110
71.5%
To solve, the easiest method I've found is to set up 2 fractions and cross multiply. so, x/100 = 105.1/147
2.54x10^3
There the answer Bestie.

Answer:
A
Step-by-step explanation:
Hihi. So, this is a nice application of interest rates as well as properties of exponentials/logarithms. As you know, the basic equation for interest rates is A= Pe^(rt) where A is your final amount, P is your initial, r is your rate of interest, and t is the time the money was accumulating interest. After cleaning up, you get in a situation due to you having e still lying around. Luckily, if you take the natural log of e, all you have left behind is the previous exponent. Thus, you can take the natural log of both sides, divide by 4, and then simplify to see that your final interest rate is ~6%
