$15 - $8 = $7.
$7 / 2 = $3.50

spends $3.50 on each card.

H̲̅ᴇ̲̅ʏ̲̅! Hope that I can help!

To do this, we need to put it into an equation. This equation is
8 +c = 15. To find out what
c is we need to subtract the 8 from both sides of the equation to make it even. 8+
c-8=
c. 15-8=7.


c=7. Becuase
c represents 2 cards, we need to divide it by 2. 7÷2=3.5.

He can spend $3.50 for each card.
