Answer: b) 15.7
<u>Step-by-step explanation:</u>
Look at the z-table (below) to find 0.2500
Notice that the value is not on the table but is between 0.2486 and 0.2517 which are located on the z-table at 0.67 and 0.68
The given value is closer to 0.2486 so use 0.67 as the z-score.
Now, let's find the x-value using the formula: 

To solve this problem you will need to use the cross product method:
1/16 of an hour → write 1 card
3/4 of an hour → write X cards
(3/4) ÷ (1/16) = X
0.75 ÷ 0.0625 = X
12 = X
Joey can write 12 Thank you cards in 3/4 of an hour.
