At a certain diner, a hamburger and
coleslaw cost $3.59, and a hamburger
and french fries cost $4.40. If french fries
cost twice as much as coleslaw, how
much do french fries cost?

Just assign each to a variable and solve as a system of equations.

h=cost of a hamburger
f=the cost of french french fries
f/2=the cost of coleslaw

h+(f/2)=3.59
h+f=4.40

f/2=0.81
f=1.62

french fries cost $1.62.
