a parking garage rents parking spaces for $ 10 per week or $ 35 per month . how much does a person save in a year by renting by the month rather than by the week ?
10 $ per week ! an year has 52 weeks . annual charges per year = 52 * 10 = 520 $ 30 $ per month ! an year has 12 months . annual charges per year = 12 * 35 = 420 $ 520 - 420 = 100 ans b
subtract(multiply(add(multiply(const_10, add(const_3, const_2)), const_2), 10), multiply(35, const_12))
