Answer :

To determine how many pounds you would spend to purchase something that costs 30 Euros, given the exchange rate is 1 Euro to 80 pounds, follow these steps:

1. Begin by noting the exchange rate, which states that 1 Euro is equivalent to 80 pounds.
2. Next, identify the amount you want to convert, which is 30 Euros in this case.
3. To find out how many pounds are equivalent to 30 Euros, multiply the number of Euros by the exchange rate.

So, calculate:
[tex]\[ \text{30 Euros} \times \text{80 pounds/Euro} = \text{2400 pounds} \][/tex]

Thus, to purchase something that costs 30 Euros, you would need to spend:
[tex]\[ \boxed{2400 \text{ pounds}} \][/tex]
