Final answer:
Denis's employer deducts $1,432 for Medicare taxes annually.
Step-by-step explanation:
To find the annual amount deducted for Medicare taxes, we need to calculate the gross annual income first. Since Denis's gross weekly pay is $1,900, we can calculate his gross annual income by multiplying it by the number of weeks in a year (52): $1,900 * 52 = $98,800.
Now, we can calculate the annual amount deducted for Medicare taxes. Medicare taxes are 1.45% of the gross annual income. So, we can calculate it by multiplying the gross annual income by 1.45%: $98,800 * 1.45% = $1,432.
Therefore, Denis's employer deducts $1,432 for Medicare taxes annually.
