Question

This equation shows how the total length Sophie has knit depends on the number of nights she has spent knitting.

t = n + 76

The variable n represents the number of nights Sophie has spent knitting, and the variable t represents the total length she has knit in centimeters. After 20 nights of knitting, how many centimeters of scarf will Sophie have knit in total?

centimeters

Answer 1

To find out how many centimeters Sophie has knitted after 20 nights, we can substitute \( n = 20 \) into the equation \( t = n + 76 \).

\[
t = 20 + 76
\]

Calculating that gives:

\[
t = 96
\]

So, after 20 nights of knitting, Sophie will have knitted a total of **96 centimeters** of scarf.
