Question 1003096
Hi there,
johny pays $30 to join the gym
plus monthly dues that are $10.
Equation showing total cost for x months
Cost = $30 + $10x
timmy’s taxis charges $1 for the first mile 
plus $0.35 per mile for every mile 
Equation showing total cost for x miles
Cost = $1 + $0.35x
Hope this helps :-)
