First, determine the weight of 330 cans with the given conditions, (330 cans) x (4 lbs / 100 cans) = 13.2 lbs Then, the price is determined by multiplying this weight to the price that the recycling center is paying, (13.2 lbs) x (25 cents / lb) = 330 cents = $3.3 Thus, Robert will be paid $3.3.
It is D because they cannot be negative feet away and if the fisherman is 12ft above water and the diver is 40ft below than 40 + 12 = 52. Hope this helps.
