# Each year, a cyber café charges its customers a base rate of $$\25$$, with an additional $$\0.30$$ per visit for the first 50 visits, and $$\0.10$$ for every visit after that. How much does the cyber café charge a customer for a year in which 72 visits are made?

42.20

Explanation

Translate the information into arithmetic. The café charges $$\ 25+\ 0.30(\text { first } 50)+\ 0.10(x)$$ (x is additional visits after 50). For 72 visits there are 50 visits with an additional 22 visits.
$$=\25+\0.30\times50+\0.10\times22$$
$$=\25+\15+\2.20$$
$$=\42.20$$
