Eduardo opened a credit card at a department store with an APR of 22.29% compounded semiannually. What is the APY on this credit card? (2 points) a 44.58% b 11.15% c 23.53% d 49.55%

The correct option is c. 23.53%.

Step-by-step explanation:

The annual percentage yield (APY) can be calculated using the following formula:

APY = (1 + r / n)^n - 1 (1)

Where;

APY =  Annual percentage yield = ?

r = Annual percentage rate = 22.29%, or 0.2229

n = Number of compounding period per year = Semiannually = 2

Substituting the values into equation (1), we have:

APY = (1 + 0.2229 / 2)^2 - 1

APY = 0.2353211025, or 23.53211025%

Rounding to 2 decimal places, we have:

APY = 23.53%

Therefore, the correct option is c. 23.53%.

answer are

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
