the school can only seat 50 students in every bus. If the school is planning on taking 360 students on a field trip. How many busses do they need. (show work) with independent variable dependent variable constant term and coefficient

Answers

so you would do 360/50
simplified you would get 36/5 this simplifies to about 7 and 1/5

so you would need 7 and 1/5 bus or 7.2 bus
but you can't have 1/5 buss so you would need to make the 1/5 into a 1 so
7+1=8
8 busses neede
50x = 360
x is the number of buses
x = 360/50 => 36/5
x = 7.2

Independent Variable: x
Dependent Variable: 360 (or y)
Coefficient: 50 (b/c of 50x)
I don't see a constant term, sorry
