Final answer:

Chanda will take approximately 3.75 hours to bake and decorate 108 cookies.

Step-by-step explanation:

To find out the time it will take for Chanda to bake and decorate 108 cookies, we can use the concept of proportions. If Chanda can bake and decorate 72 cookies in 2.5 hours, we can set up a proportion:

72 cookies / 2.5 hours = 108 cookies / x hours

Now, we can cross-multiply and solve for x:

72 * x = 108 * 2.5

x = (108 * 2.5) / 72

x ≈ 3.75 hours

Therefore, it will take Chanda approximately 3.75 hours to bake and decorate 108 cookies.
