Answer 1

Christina used 3 cm of tape per present (unit rate). With 39 cm of tape, she could wrap 13 presents. The provided answer choices are incorrect as 13 is not listed.

Step-by-step explanation:

The question asks us to solve how many presents Christina wrapped if she used 39 centimeters of tape, given that she used 27 centimeters to wrap 9 presents. We will solve this using unit rates.

First, we find the unit rate of the tape used per present:

27 cm of tape / 9 presents = 3 cm/present.

Now, we use this unit rate to find out how many presents can be wrapped with 39 cm of tape:

39 cm of tape / 3 cm/present = 13 presents.

Therefore, Christina wrapped 13 presents using 39 centimeters of tape. The answer choices provided in the question seem to be incorrect as none match the calculated answer. It is important to always double-check the answer choices with the calculated result.
