Bridgette used 35 centimeters of tape to wrap 7 presents. How much tape will Bridgette need in all if she has to wrap 8 presents? Solve using unit rates.

Bridgette used 35 cm of tape to wrap 7 presents.

So, she used 35/7 = <<35/7=5>>5 cm of tape per present.
Therefore, she will need 5 x 8 = <<5*8=40>>40 cm of tape if she has to wrap 8 presents.
Therefore, Bridgette will need 40 cm of tape in all. Answer: \boxed{40}.
