A stock price has a price of $7.50 per share at the beginning of the week. At the end of the week, the stock price is $9.45 per share. (a) What is the percent increase in the stock's price per share for the week? (b) The $7.50 price per share represents a 40% decrease from the price per share last week. What was the price per share last week? (c) The stock price is projected to increase by 40% from the $9.45 per share price by the end of the year. What is the projected price of the stock?

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25

step-by-step explanation:

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
