Can you solve and explain how. i dont have any idea : (

From the expression 2f + 5(8-f), we know that Karla caught f purple dot fish, and (8-f) green dot fish, because green dot fish gives 5 points.

2f -points for the purple dot fish, f is a number of the purple dot fish.

5(8-f) - points for the green dot fish, (8-f) is a number of the green dot fish.

So,

altogether she made 8 attempts.

One attempt cost 50 cents,

8 attempts cost 8*50=400 cents = $ 4.

Answer is B. 4 (dollars).

b is the answer that makes most sense

step-by-step explanation:

i got 86 for this

hope this !
