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 15 people equals $ ___. (Input whole number only.)
100+4n is the equation so you have to fill in the gaps. The equation would turn out like this: 100+4(15) which turns to 100+60 and then the answer would be $160.
