At the Annual 7th grade breakfast, the teachers buy the students a breakfast of bagels and juice. The table below shows the relationship between the number of students attending the breakfast and the total cost. If C=mS, where Cis the cost of S students and m is the constant of proportionality, what is the value of x? In June, the 7th grade teachers bought breakfast for150 students. What was the total cost? Show your work.

$187.5

Step-by-step explanation:

if each student costs 1.25 dollars for their meal then you do 150 times 1.25 and get 187.5

d

step-by-step explanation:

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
