C. The cost of 5 notebooks is less than the cost of 3 + a $2 pen.
Process of elimination:
The greater or less than sign is open towards 3x + 2.
Get rid of the ones that say 5x is greater .
So A. And D. Are not an option
Now you have to put the pieces together.
Answer B. Sounds right until you get to the “$2-off coupon”
In the equation above it says 3x PLUS 2.
$2 off means subtraction. So we automatically know C is the only other answer.
