java house charges $ 4.25 for a cup of coffee that costs a total of $ 3.85 to make . cup ' o ' joe charges $ 4.80 for a cup that costs $ 4.65 to make . if java house sells 55000 cups of coffee , how many must cup ' o ' joe sell to make at least as much in total gross profit as its competitor does ?
java : profit / cup = 4.25 - 3.85 = 0.4 : no of cups = 55,000 : gross profit = 55,000 * 0.4 = 22,000 joe : profit / cup = 0.15 : gross profit = 22,000 : no of cups = 22,000 / 0.15 = 220,000 / 1.5 ( only closes is 146,667 ) answer e
divide(divide(multiply(55000, subtract(4.25, 3.85)), subtract(4.8, 4.65)), multiply(const_10, const_1000))
