Answer :
Let "c" be the number of cards Caleb has and "a" the number of cards Adam has.
If Caleb has four times as many cards as Adam, we can write:
[tex]c=4a[/tex]if Caleb has 608 cards, we can write:
[tex]c=608[/tex]Combining both, we have:
[tex]4a=608[/tex]Then, we can calculate a as:
[tex]\begin{gathered} 4a=608 \\ a=\frac{608}{4}=152 \end{gathered}[/tex]Answer: 4a = 608, a = 152.
