Explanation:

A stock you own earned: $200, $500, $100, and $700 over the last four years.

We need to find the annual gain in value over the four years. We know that,

Mean = sum of observations/total no. of observations

Put all the values,

So, the required mean annual gain is equal to $375.

hi : ) i found this so i hope this !

"we first find value of tax in dollars.

the difference between the two prices   is: 23. 54 - 22 = 1.54

therefore the sales tax in dollars is 1.54

the tax % will be   (amount of tax / original cost price ) × 100

(1.54 / 22) × 100  → (0.07) × 100 =   7

so the tax rate is 7%

we can double check the answer.

7 % of 22   → (7/100) × 22 → 0.07 × 22 = 1.54

22 + 1.54 = 23.54"
