The given expression actually represents the amount left with Jared after making those purchases.
Jared has $32
He purchases 5 packs of trading cards at $3 each.
So amount spent = 5 × 3 = $15
The cost display book = $3
And the cost of another display book = $7
So total amount spent
= (5×3) +3 + 7
= 15 + 3 + 7
= $25
The expression
32- [(3×5)+3+7)
= 32 - 25
= $7
$7 is the amount left with Jared after he makes all these purchases.
