Juan is buying soda for a class party. he can go to the vending machine and buy 12-oz cans for $0.60 each, to the corner store and get 20-oz bottles for $0.95, or to the grocery store and get 32-oz jugs for $1.55. Which is the best deal?

Best deal is corner store

Step-by-step explanation:

LCM is 480 oz

480 oz of the Vending Machine would be £24 (0.60 x (480/12))

480 oz of the Corner Store would be £22.80 (0.95 x (480/20))

480 oz of Grocery store would be £23.25 (1.55 x (480/32))

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.
