To find the cost of one pencil using the equation \( y = 0.19x \), where \( y \) is the total cost and \( x \) is the number of pencils, we can substitute \( x = 1 \) (for one pencil).
\[ y = 0.19(1) = 0.19 \]
Thus, the cost for one pencil is $0.19.
The cost of a pencil is described by the equation y=$0.19x . What is the cost for one pencil.?
