Question

This equation shows how the number of spools of thread that Zoe has left is related to the number of dresses that she sews.

s = –d + 12

The variable d represents the number of dresses Zoe has sewn, and the variable s represents the number of spools of thread remaining. How many dresses can Zoe sew, at most, and still have 4 spools of thread left?

dresses

Answer 1

To find out how many dresses Zoe can sew and still have 4 spools of thread left, we will use the equation provided:

\[
s = -d + 12
\]

We know that \( s = 4 \) (the number of spools remaining). We can substitute this value into the equation and solve for \( d \):

\[
4 = -d + 12
\]

Now, let's solve for \( d \):

1. Subtract 12 from both sides:

\[
4 - 12 = -d
\]
\[
-8 = -d
\]

2. Multiply both sides by -1:

\[
d = 8
\]

So, Zoe can sew at most **8 dresses** and still have 4 spools of thread left.
