Gordon used 12 centimeters of tape to wrap 3 presents. How much tape will Gordon need in all if he has to wrap 4 presents? Assume the relationship is directly proportional.

Answer

Solution: Since the relationship is directly proportional, we can set up a proportion to solve for the amount of tape needed for 4 presents.

If 12 cm is used for 3 presents, then for 1 present, the tape used is 12 cm / 3 = 4 cm.

For 4 presents, the tape needed is 4 cm/present * 4 presents = 16 cm.

Answer: 16 centimeters
