Answer:one pen = $1.50
Step-by-step explanation:
See picture for the math if that helps
Using p for pens, h for highlighter,
A for first equation
B for second equation
I used equation A to reduce to a usable substitute by dividing all by 3
And then isolating “h”.
Now substitute the value of “h” into equation B and solve for “p”
P=$1.50
To check your work, substitute p ($1.50) into equation B and solve for “h”
h=$4.00
Now substitute the p and h values into either equation A or B and solve, they equal the numbers given
