Abby has $32 to spend on party supplies. After buying 9 packs of noisemakers, she has $20 left. How much did each pack of noisemakers cost?

A

$0.75

B

$1.15

C

$1.33

D

$12.00

$1.33

Step-by-step explanation:

32-20 = 12

12/9 = $1.33

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.

6mm^3 or .6cm^3

factor trees are nice.
