Can I ask what values 40, 12, and 500 stand for?

40(4)+ 12(2)  <= 500?

160 + 24 = 184     Yes it  is safe to ride

Okay. I mean I guess I won't need them if we are just plugging the numbers in.

 

We have the equation \(40c + 12a \leq 500\).

 

Plugging in \(4\) for c and \(2\) for a,

 

we get:

 

\(40(4) + 12(2) \leq 500\)

 

\(= 160 + 24 \leq 500\)

 

\(= 184 \leq 500\).

 

Since \(184\) is less than \(500\), the boats are safe. 

 

Therefore, Judah's family can ride the bumper boats safely.

 

So the answer is \(\boxed{yes}\).
