Answer:
Natalie got 3, Veronica got 9.
Step-by-step explanation:
N = Natalie
If Veronica got 3 times as many as Natalie, then she got 3N.
Add them together:
N + 3N = 12
4N = 12
N = 3
Therefore,
Natalie got 3 (N = 3)
Veronica got 9 (3N = 3 x 3 = 9)

$16.05
Step-by-step explanation:
50% of 10.00
0.50 x 10.00 = 5.00
10.00 + 5.00 = 15.00
7% of 15.00

15.00 + 1.05 = 16.05
Two fields at a state park are 1,000 meters from each other. On a map, the two field are 8 centimeters apart. What scale is the map using?
Answer:
Step-by-step explanation:
Given
two fields are 1000 meters from each other on a map, and the two fields are 8cm apart.
We have to express the scale of the map as unit of measure. So we need to figure out how many actual meters for each cm in the map.
If 1000 meters is equal to 8 cm, how many meters (let's calls this x) is equal to 1 cm?
Therefore, the scale is
In the given question it is important to take note of every minute details that are given in the question. using these details the answer to the given question can be easily reached.
Let us assume the common ratio to be x.
Then
x + 9x = 81
10x = 81
x = 81/10
= 8.1
A s we already know that the ratio of chaperones to students is 1:9
