Find the first and third quartiles for the cost of admission:
$13.90, $24.50, $18.99, $29.98, $23.95.

A. First Quartile=$15.50 and Third Quartile=$20
B. First Quartile=$15 and Third Quartile=$ 27.24
C. First Quartile=$16.45 and Third Quartile=$ 27.24
D. First Quartile=$16.45 and Third Quartile=$32

C. just choose C. if it isn't right just tell me.

i think it's b

step-by-step explanation:

because the graph is 2 above (0,0)

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
