Solution: We are given:
1 Mexican Peso = 7.1492 Japanese Yen ------------ equation 1
We have to find how many Mexican Pesos are equal to 1 Japanese Yen.
Divide both sides of equation by 7.1492 and multiply both sides by 1, we have:
Mexican Peso
Japanese Yen
Mexican Peso
Japanese Yen
Therefore, 1 Japanese Yen is approximately equal to 0.1399 Mexican Peso

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
<h3>
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.
