Let n be the amount of time it takes william to cut the lawn. Then Shelly takes
n-2 hours. So:
1/n+1/n-2=1/3
3(n-2)+3n=n²-2n
6n-6=n²-2n
n²-8n+6=0
Using the quadratic formula, we get a positive value of 7.1623 hrs as the amount of time william takes working alone, and 5.1623 as the amount of time Shelly takes working alone

Answer:
12 choices
Step-by-step explanation:
There are 3 possible flavors Zoe can choose from: vanilla, chocolate, and strawberry.
Meanwhile, there are 4 possible toppings Zoe can choose from: walnuts, sprinkles, and chocolate fudge and cookie crumbs.
Each flavor can go with each topping, so we just multiply these two numbers together:
3 * 4 = 12
Zoe has 12 choices.
