The number of kids in your group is 12.
<u>Step-by-step explanation:</u>
Let the number of kids=x
number of adults=y
total number of people=20
x+y=20(1)
cost of kids ticket=$4
cost of adults' ticket=$6
total cost=$96
4x+6y=96(2)
solving (1) and (2)
we get x=12
y=8
number of adults in the group y=8
number of kids in the group=12

There are 180° in a triangle so you do
180- (30+30)
=180 - 60
=120
Therefore the answer is x = 120
Answer:
11.70%
Step-by-step explanation:
Given;
Interest paid = $44
Principle amount = $1,153
Time = 119 days =
= 0.326 years
Now,
the interest is calculated as:
interest = Principle × Rate of interest × Time
thus,
$44 = $1,153 × Rate of interest × 0.326
or
Rate of interest = 0.1170
or
in percentage = Rate × 100 = 0.1170 × 100 = 11.70%
B.) y = 30x + 55
y should equal the total cost of the service while x is the number of hours it takes.
