Answer:

8 cookies left to be baked.

Step-by-step explanation:

Together both of them bakes = (1/3) + (2/5)

                                                 =  \frac{5}{15} +\frac{6}{15}

                                                 = \frac{11}{15} cookies.

So they have baked: (11/15) * 30 = 22 cookies together.

cookies left to be baked: 30 - 22 = 8 cookies.
