A) A pack of 8 batteries cost £3.99 how much dose each battery cost? ( give your answer in penny ?) B) A pack of 6 batteries of the same type costs 2.79. By calbattery determine if this is a better value. You must show your working out?

A). 50 penny

B) This type of battery is cost effective.

Step-by-step explanation:

A) A pack of 8 batteries cost 3.99 pounds so one battery will cost = 3.99/8 = 0.499 pound

Since 1 pound = 100 penny

So 0.499 pound = 100×0.499 = 50 penny

B). A pack of 6 batteries of the same type costs 2.79 pounds

So one battery will cost = 2.79/6 = 0.465 pound  or 47 penny

Now we say that type A batteries are costlier than B. Therefore B type batteries are of a better value.

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.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
