3) 60 miles apart.
4) 60 rotations
5)45/p where p is the number of pages.
Step-by-step explanation:
1) One out of every five people who buy ice cream buys vanilla ice cream. If a store sells 125 ice cream cones in one day, about how many will be vanilla?
We need to solve this problem using a proportion and solving for x:
25 ice cream cones will be vanilla.
2. Taxes on a house assessed at $64,000 are $1500 a year, If the assessment is raised to $85,000 and the tax rate did not change, how much would the taxes be?

3. I have a map where Indy and Ft. Wayne are 3 centimeters apart. Kokomo and Indy are 1.5 cm apart on the map. If I know that Indy and Ft. Wayne are really 120 miles apart, how far would Indy and Kokomo be in real life?
To solve this, first we have to remember that 1 mile equals 160934 cms. Therefore, 120 miles would be 19312080 cms.
Indy and Kokomo are 9656040 cms apart, this equals 9656040/160934 = 60 miles apart.
