An 8 pack of beaded necklaces cost $21.92. what is the unit price per necklace??

$2.74

Step-by-step explanation:

Given

8 pack of beaded necklaces cost $21.92,

Price per necklace = total cost of the 8 packs divided by the number of packs

That’s

= $21.92/8

= $2.74

Each necklace cost $2.74

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.

47 - 90 = 43

43 - 180 = x

x = 137
