Answer:
30
Step-by-step explanation:
Each z-score = 1 standard deviation from the mean, so 18 + (6 x 2) = 30

Step 1&2 are correct as he did the process right.
So, he must of multiplied or simplified wrong
So, 4×8= 32
And 7×8=56
As you may have noticed he has gotten 20/50 instead of 32/56
Where Pedro messed up is step 3
