It costs $100 to rent the bowling alley, plus $4 per person. The cost for any number (n) of people can be found using the expression 100 + 4n. The cost for 10 people equals $? what is my answer?
Cost = 100 + 4(10) = 100 + 40 = $140
n = number of people and you need to find for 10 people, put 10 instead of n
100 + 4(10)
100+40=140
