Step-by-step explanation:

x - number of senior citizen tickets sold

y - number of child tickets sold

1st day: 3x + 6y = 102

2nd day: x + 12y = 184

2 (3x + 6y = 102)

= 6x + 12y = 204

-1 (x + 12y = 184)

= -x - 12y = -184

6x + 12y = 204

-x - 12y = -184

= 5x = 20

x = 4

3(4) + 6y = 102

= 12 + 6y = 102

= 6y = 90

y = 15

Answer:

One senior ticket is $ 4.00 and one child ticket is $ 15.00

Hope this helps! :D

Answer: 5% interest rate

==============================================

Work Shown:

The given values are

A = 5205.75

P = 3500

n = 4

t = 8

-----

Plug those values in. Isolate r.

A = P*(1+r/n)^(n*t)

5205.75 = 3500*(1+r/4)^(4*8)

5205.75 = 3500*(1+r/4)^(32)

3500*(1+r/4)^(32) = 5205.75

(1+r/4)^(32) = 5205.75/3500

(1+r/4)^(32) = 1.48735714285714

1+r/4 = (1.48735714285714)^(1/32)

1+r/4 = 1.01248355256014

r/4 = 1.01248355256014-1

r/4 = 0.01248355256014

r = 4*0.01248355256014

r = 0.04993421024056

r = 0.0499

Multiply this r value by 100 to convert to a percentage

100*r = 100*0.0499

100*r = 4.99%

Rounding to the nearest tenth, we get 5.0% or just 5%

Prime number = numbers greater than 1, they only have two factors. 1 and the number itself.

composite number = positive integer, multiplying two smaller positive integers.

prime fact. = finding what the prime numbers are and then multiplying them.

factor tree = pretty self-explanatory. all of the numbers spread out into a way so that you can multiply them. for example, (image attached). hope this helps!!
