Answer

Explanation:

Step1: Identify the value of x

The number of weeks is 4, so $x = 4$.

Step2: Substitute x into the equation

Substitute $x = 4$ into $y=1.8x + 1.2$. We get $y=1.8\times4+1.2$.

Step3: Calculate the value of y

First, calculate $1.8\times4 = 7.2$. Then $7.2+1.2=8.4$.

Answer:

B. 8.4 pounds
