We want to see which offer is the best one to buy 40 batteries, by using algebra we will see that the best offer is offer-B

How to find the best offer?</h3>
Here we just need to see which would be the cost of 40 batteries which each offer.
For offer-A, a pack of 4 costs £2.52 and we have 1/3 off.
For 40 batteries the cost will be 10 times the above quantity, we get:
10* £2.52 = £25.20
But there is a 1/3 off, so the cost would be 2/3 of the above quantity:
£25.20*(2/3) = £16.80
For offer-B we know that a pack of 5 costs £2.75, so you need to buy 8 of these. And for each 3 you get one free, so you need to buy 6 (and get 2 free ones). The cost of 6 of these is:
6*£2.75 = $16.50
From this, we can conclude that offer-B is the best one.

Answer:
5
Step-by-step explanation:
200% × x = 20. x = 10. 50% of a number = 50% × 10 = 50÷100×10 = 0.5 × 10 = 5.
10/1 thats how you will get an improper fraction
C 39.99 adding it all together
Just divided the numerator(the top number) by the denominator(bottom number)
