**Answer:**

The actual SAT-M score marking the 98th percentile is 735.

**Step-by-step explanation:**

**Problems of normally distributed samples are solved using the z-score formula.**

In a set with mean and standard deviation , the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

**In this problem, we have that:**

**Find the actual SAT-M score marking the 98th percentile**

This is X when Z has a pvalue of 0.98. So it is X when Z = 2.054. So

**Answer:**

2,400.

**Step-by-step explanation:**

Since the shopkeeper bought 100 blankets at $ 2000 each, he spent a total of $ 200,000. He wants to make a total profit of 14% through his sale, that is, he wants to make sales for $ 228,000 (200,000 x 1.14).

Since he sold 10 defective blankets at $ 1200 each, he recovered a total of $ 12,000. Therefore, he has $ 216,000 (228,000 - 12,000) left to achieve his goal, through the sale of 90 blankets. Therefore, you must sell each blanket for $ 2,400 (216,000 / 90) to make the desired profit.

**Answer:**

$35,100

**Step-by-step explanation:**

Since you're looking for '<u>how much it is worth after a year,' </u> you would need to subtract the 22% from 45,000.

$45,000 - 22% = $35,100
