eight identical machines can produce 360 aluminum cans per hour . if all of the machines work at the same constant rate , how many cans could 5 such machines produce in 7 hours ?
"8 machines / 360 cans = 5 machines / x cans 8 x = 1800 x = 225 ( 225 ) ( 7 hours ) = 1575 cans . the answer is e ."
subtract(multiply(7, 360), multiply(7, divide(multiply(5, 360), add(const_4, const_4))))
