I think it's C. There are 7 bricks in the first row of the structure.

Given the function: b(r) = 7 + 4(r-1), r is the row of the structure.

Find b, when r = 1. How many bricks are in row 1?

b(1) = 7 + 4(1-1)

b(1) = 7 + 0

b(1) = 7

Answer: C.

The infant should be given 700 mg of Claforan every 8 hours.

Step-by-step explanation:

This question involves proportional measures, and asks how many mg of Claforan the infant should be given every 8 hours.

For each kg, the infant should be given 50 mg of Clarofan. The infant weighs 14 kg, so he should be given 14*50 = 700 mg of Claforan every 8 hours.
