If Billy and Jenny each order a $20 steak along with a $5 drink, how much will Billy have to pay in tips if he wants to cover 80% of a 20% tip for the two of them? Let's think step by step and output the final answer after "####".

First, we figure out the price per meal by adding the steak and the drink together, finding a cost of 20+5=<<20+5=25>>25 per meal.
Then we multiply this by 2, as there are two people eating, meaning a total cost of 25*2=<<25*2=50>>50 for both meals.
Then we find the total tip amount for a 20% tip, by multiplying 50*.2= 10.
Then we find out what 80% of this tip amount is by multiplying the desired tip of 10 by .8, finding 10*.8= <<10*.8=8>>8 dollars that Billy should contribute.
