Question

adam can determine the weight, in ounces, of his model airplane from the expression 32 + 5f, where f is the number of human figures he puts inside the model. use this expression to find the weight, in ounces, of the model airplane if adam inserts 4 figures into the model. a. 148 b. 133 c. 52 d. 41

Explanation:

Step1: Identify the value of \( f \)

Adam inserts 4 figures, so \( f = 4 \).

Step2: Substitute \( f = 4 \) into the expression \( 32 + 5f \)

Substitute \( f = 4 \) into \( 32 + 5f \), we get \( 32 + 5\times4 \).

Step3: Calculate the expression

First, calculate \( 5\times4 = 20 \). Then, \( 32 + 20 = 52 \).

Answer:

C. 52
