The pattern 7, 8, 10, , follows the rule multiply by 2, then subtract 6. What are the next two terms? Question 9 options:

14, 28

14, 22

20, 28

20, 22

14 22

Step-by-step explanation:

i think it is

A) about 50 cents

B) about 47 cents; the 6-pack is better

Step-by-step explanation:

Since 8 batteries cost a total of £3.99, say each one costs x. Then:

x + x + x + x + x + x + x + x = 3.99

8x = 3.99

Divide both sides by 8:

x = 3.99/8 = 0.499 ≈ 50 cents

So each battery in this 8-pack costs about 50 cents.

Now take a look at the 6-pack. Suppose each battery in there costs y.  Then:

y + y + y + y + y + y = 2.79

6y = 2.79

Divide both sides by 6:

y = 2.79/6 = 0.465 ≈ 47 cents

Clearly, we can see that the batteries in the 6-pack set cost less than the batteries in the 8-pack set, so the better value would be buying the pack of 6 batteries.
