we know that
The equation of a exponential growth function is equal to

where
y is the average annual salary
x is the number of years
r is the rate of change
a is the initial value
In this problem we have

substitute


For x=4 years

Answer:
flipped
Step-by-step explanation:
A reflection is a transformation representing a flip of a image. images can be reflected in a plane, line, and point. When reflecting a image/figure in a line or in a point, the image is congruent to the preimage. A reflection maps every point of a figure to an image across a fixed line.
Answer:
You can use grouping, quantity and value to solve this question.
Child admission = $5.50
Adult admission = $8.90
Friday sales (Quantity):
Child = x
Adult = 4x
Total sales = 5x
Friday sales (Value):
Child = $5.50
Adult = 4 × $8.90
= $35.60
Total sales = $986.40
1 group = $5.50 + $35.60
= $41.10
Number of groups = $986.40 ÷ $41.10
= 24
The number of child tickets sold is 24.
