In an online catalog, the price per packet for vegetable seeds, v, is $0.79 plus a $3.99 shipping fee. the price per packet for flower seeds, f, is $1.89 plus a $5.49 shipping fee. write an expression to represent the combined cost of the seeds, and then simplify your expression.

Total cost of the seeds v and f is 12·16

Step-by-step explanation:

Price per packet for vegetable seeds v is 0·79

shipping fee per packet for vegetable seeds v is 3·99

Total cost of vegetable seeds v is price per packet of v shipping fee

Total cost of vegetable seeds v is   0·79 ⁺ 3·99

                                                          4·78

Price per packet for flower seeds f is 1·89

shipping fee per packet for flower seeds f is 5·49

Total cost of flower seeds f is price per packet of f shipping fee

Total cost of flower seeds f is   1·89 ⁺ 5·49

                                                  7·38

Total cost of the seeds v and f v₊p

                                                    4·78 ⁺ 7·38

                                                    12·16

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.
