Answer:
The number of children tickets sold was 610.
Step-by-step explanation:
Let
x ----> the number of adults tickets sold
y ----> the number of children tickets sold
we know that
x+y=1710 -----> equation A
50x+25y=70250 ----> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
The solution is the point (1100,610)
therefore
The number of children tickets sold was 610.
9514 1404 393
Answer:
$67,200
Step-by-step explanation:
The amount if interest is given by the formula ...
I = Prt
where P is the amount invested, r is the annual rate, and t is the number of years. Here, we want to find P when r = 0.05 and t = 1/2 such that I = 1680.
P = I/(rt) = $1680/(0.05·0.5) = $1680/0.025
P = $67,200
The amount invested was $67,200.
