Q. This equation shows how the total number of hair bands Sally owns is related to the amount of money she spends on additional hair bands.

\newline

h = 6d

\newline

The variable

d

represents the amount of money she spends on additional hair bands, and the variable

h

represents the total number of hair bands she owns. With

\$1

to spend on new hair bands, how many total hair bands can Sally own?

\newline

_____ hair bands

Identify Variable: Identify the variable that $\$1$ corresponds to. $d$ represents the amount of money spent on additional hair bands. So, $\$1$ gives the value for $d$ .
Substitute Value: We know that $d = 1$ . $\newline$ Plug in the value for $d$ in $h = 6d$ . $\newline$ $h = 6d$ $\newline$ Substitute $d$ with $1$ . $\newline$ $h = 6 \times 1$
Solve for Total: $h = 6 \times 1$ . $\newline$ Solve for $h$ . $\newline$ $h = 6 \times 1 = 6$ $\newline$ Therefore, the total number of hair bands Sally can own with $\$1$ spent is $6$ .
