4.) a concert charges $24.50 per daily adult ticket and $13.75 per child's ticket. a group of 90 people paid $1560.00 for tickets. write a system of equations that could be used to find x, the number of adult tickets purchased, and y, the number of children's tickets purchased?

i found two solutions,   n = 2 • ± √3 = ± 3.4641

step-by-step explanation:

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
