A store sells notebooks for $\$3$ each and pens for $\$2$ each. Ari spent exactly $\$40$ on $n$ notebooks and $p$ pens. Which equation represents this situation?

$3n + 2p = 40$

$2n + 3p = 40$

$5(n + p) = 40$

$3n + 2p + 40 = 0$

Show answer and explanation

Answer: A

The notebooks cost $3n$ dollars and the pens cost $2p$ dollars. Their total is 40, so $3n + 2p = 40$ .

Choice B attaches each price to the wrong item.
