Problem: 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 6 hours ?
Rationale: 8 machines / 360 cans = 5 machines / x cans 8 x = 1800 x = 225 ( 225 ) ( 6 hours ) = 1350 cans . the answer is d .
annotated_formula: subtract(multiply(6, 360), multiply(6, divide(multiply(5, 360), add(const_4, const_4))))
