Answer:

Step-by-step explanation:
.0138
We need 1 number to the left of the decimal
1.38 * 10^ something
We moved it 2 places to the right, that means our exponent is -2. If we had moved it to the left, our exponent would have been positive
1.38 * 10^ -2
1/3 hour = 20 minutes
1 1/2 dozen = 12 + 6 = 18 cookies
18 cookies x 3 (3 sets of 20 minutes = 1 hour) = 54 cookies per hour
