There are less than 50 students in the class. today, only 97.5% of the class is here. how many students are in this class?

the of students in the class are students  

the   of students here in class today are

Step-by-step explanation:

Let

x-------------> total students in the class

y------------- >number of the students here in class

so

we know that

the interval solution for x is all whole numbers belong to the interval

 the solution will be a number belonging to the interval   such that when multiplying by it gives me a whole number 

see the attached excel table 

the of students in the class are students  

the   of students here in class today are

tickets for the harlem globetrotters

show at michigan state university in

2010 cost $16, $23, or, for vip seats, $40.

total revenue = 16x + 23y + 40z

if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, sales of all three kinds of tickets would

total $46,575.

16x + 23y + 40z = 46575, how many of each kind of ticket would

have been sold?

solve for x, y and z

x − 9z = 0

x − y − z = 55

16x + 23y + 40z = 46575

x = 1170

y = 985

z = 130

welcome!

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!
