writing and evaluating a function that models a real - world situation: basic
rafael needs to read 4 novels each month.
let n be the number of novels rafael needs to read in m months.
write an equation relating n to m. then use this equation to find the number of novels rafael needs to read in 19 month
equation:
number of novels in 19 months: novels

Explanation:

Step1: Define the relationship

Rafael reads 4 novels per month. So the number of novels \( N \) is 4 times the number of months \( M \). The equation is \( N = 4M \).

Step2: Substitute \( M = 19 \)

Substitute \( M = 19 \) into the equation \( N = 4M \). So \( N = 4\times19 \).

Step3: Calculate the value

\( 4\times19 = 76 \).

Answer:

Equation: \( N = 4M \)
Number of novels in 19 months: 76 novels
