1. You should use subtraction (20-12.68=7.32)

2. You should use multiplication

3. You need to know 5 boxes and $5.29

4. You need to know 10 packages and 2 cases

Step-by-step explanation:

I hope this helpss!!

i believe the answer is d.

hope it you! : d

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.
