Answer:
140 child tickets were sold
Step-by-step explanation:
a = number of adult tickets
c = number of child tickets
a+c = 350
6.50 c + 8.50a = 2695
Multiply the first equation by -8.50 together
-8.50c -8.50c =-2975
Add this to the second equation to eliminate a
-8.50c -8.50c =-2975
6.50 c + 8.50a = 2695
---------------------------------
-2c + 0a = -280
Divide by -2
-2c/-2 = -280/-2
c = 140
Answer:
15 minutes
Step-by-step explanation:
Divide 12 yards by 4/5 yards.
12 ÷ 4/5 =
12 * 5/4 =
15
Thus, it would take the ant 15 minutes to crawl 12 yards.

No actual study was done, only observation.
Given:
Growth rate = 30% decrease
To find:
The growth factor associated with the given growth rate.
Solution:
The general exponential function is:
Where, a is the initial value, r is the growth rate in decimal and is the growth factor.
It is given that the growth rate is 30% decrease. So,
Now,
Therefore, the growth factor is 0.7.
