I’d say his estimate isn’t that reasonable. Including tax they’re 15.75 let’s round that up to 16, 16*3=48 all three books would be under 48$, so he’d have just enough to buy all of them.

Answer:

I'm pretty sure he isn't being resonable because 15.75 plus tax, which is .08 or 0.10 cents, would be $16.

So let's do the math:

$16 x 3 = 48

And the gift card has $50 on it, so yeah he would have $2 to spare.

I hope this helps and please mark as brainliest!<3
