Answer:
.36
Step-by-step explanation:
To find the decay factor
y = a(1-b)^x
b = 1-rate of decrease
= 1-64%
= 1-.64
= .36
Answer:
y intercept is (0, 1)
slope is 3
equation is y = 3x +1
Step-by-step explanation:
You find the y intercept when x equals 0 and you can see that on the table that is 1.
You find slope by y2-y1 divided by x2-x1. if you pick (0,1) and (1,4) it is 4-1/1-0 which equals 3.
Therefore the equation is y = 3x + 1 in slope intercept form because the slope is 3 and y int is 1.
Let
x-----------> the number of kids
y----------> the number of adults
we know that
2.5x+6y=$7150---------> equation 1
x=2y-------------> equation 2
substitute 2 in 1
2.5*[2y]+6y=7150-----> 5y+6y=7150----> 11y=7150-----> y=650
x=2y----> x=2*650----> 1300
the answer is
the number of kids is 1300
