A) A pack of 8 batteries cost £3.99 how much dose each battery cost? ( give your answer in penny ?) ____________________________
just olya [345]

Answer:

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.
