500+(x115)=2685
the 500 is the money the club is putting towards the trip. the x is the number of club members. the 115 is the cost each member will pay to go on the trip.
subtract 500 from each side leaving you with
(x115)=2185
divide each side by 115
x=19
there are 19 club members going on the trip.

Direct variation is
y=kx
subsitute
-6=-36k
diivde both sdies by -36
1/6=k
the equation is
y=1/6x or B
Volume of a volleyball (a sphere) = 4/3πr³
= 4/3π(11.4)³
= 1975.392π
= 6210 cm³ (to 3 significant figures)
The volume of a volleyball with a radius of 11.4 cm will be 6210 cm³.
