Answer:
12 cows - 48 legs
4 ducks- 8 legs
- there are many different numbers you can do but if you want to change the numbers and have more ducks then: for every one cow you take away two more ducks.
Step-by-step explanation:
22 total animals
56 total legs
ducks have 2 legs
cows have 4 legs
12 times 4 = 48 ( 12 cows with 4 legs each cow = 48 legs)
4 times 2 = 8 ( 4 ducks with 2 legs each duck = 8 legs)
10.20 x 9 = 91.8
( It's William and nine/eight friends, since they're dividing it among ALL people we count William in. )
A: William and nine friends <span>divided the bill evenly. If each person paid $10.20, what was the total bill?
</span>
10.20 x 10 = 102
B: <span>At a restaurant, William and eight friends divided the bill evenly. If each person paid $10.20, what was the total bill?
10.20 x 9 = 91.8
C: </span><span>At a restaurant, William and nine friends divided the bill evenly. If the total bill was $91.80, what did each person pay?
91.80 x 10 = 918
D: </span><span>At a restaurant, William and eight friends divided the bill evenly. If the total bill was $91.80, what did each person pay?
</span>91.80 x 9 = 826.2
So, your answer is B
