on rainy mornings , mo drinks exactly n cups of hot chocolate ( assume that n is an integer ) . on mornings that are not rainy , mo drinks exactly 5 cups of tea . last week mo drank a total of 22 cups of tea and hot chocolate together . if during that week mo drank 8 more tea cups than hot chocolate cups , then how many rainy days were there last week ?
"t = the number of cups of tea c = the number of cups of hot chocolate t + c = 22 t - c = 8 - > t = 15 . c = 7 . mo drinks 5 cups of tea a day then number of days that are not rainy = 15 / 5 = 3 so number of rainy days = 7 - 3 = 4 b is the answer ."
subtract(add(const_4, const_3), divide(divide(add(22, 8), const_2), 5))
