Question

Donna teaches dance in groups of five students. She rents a hall for the dance classes at $450 per month. She charges $40 per hour per student. Donna teaches four groups of students, and her net earnings per month are $4,350.

If each student learns dance for the same number of hours, write an equation that can be used to calculate the number of hours each student learns dance in a month.

Answer 1

@phi

Answer 2

What do you think you would do first?

Answer 3

40h * 4 = 4,350 ?? I don't know really...

Answer 4

I know that there has to be 40h but idk what should come after that

Answer 5

I am thinking it would be something like \(\huge\frac{4350}{40}/4=h\)

Answer 6

do you see where I am coming up with those numbers?

Answer 7

yes

Answer 8

(4350/40) /4 = h

write it like this?

Answer 9

That would probably be the best that I could think of but lets see if we might be able to get @dumbcow 's opinion.

Answer 10

(4350/40) /4 = h
(4350/40) = 108.75
108.75 / 4 = 27.1875
h = 27.1875

Answer 11

whoops should be 5 not 4

Answer 12

oh

Answer 13

each group (4 groups) has 5 students, so she has like 20 students total

Answer 14

wait so should the number be 20 in the equation?

Answer 15

oh well then it should be \((\huge\frac{4350}{40})/4*5\)

Answer 16

I must have missed the part about the 4 groups

Answer 17

(4350/40) /20 = h
(4350/40) = 108.75
108.75 / 20 = 5.4375
h = 5.4375

Answer 20

just want to make sure that this is correct? :)

Answer 21

Answer 22

h is the number of hours each student does.

Four groups, 5 students per group, so 20 students total.

20 students at $40 per hour, so 20*$40 or $800 per hour. 800h would give the $ amount for h, the number of hours

Then subtract the money she spends renting the dance hall, $450.

800h - 450 = 4350
