Question

Raymond is buying boxes of party favors for his son's birthday party. He has to decide how many boxes he should purchase.
A formula for this scenario is
c=nz/f
where
c=number of children at the party
n=number of party favors per box
z=number of boxes
f=number of favors each child will get
Rewrite the equation to solve for the number of boxes of party favors Raymond should purchase.

Answer 1

c=nz/f, need to solve for z
cf=nz (multiply both sides by f)
z=cf/n (divide both sides by n and switch sides)?
