A sign reads 8 pounds for 15$ how much will someone have to pay for 10 pounds?

Answer 1

To find out how much someone will have to pay for 10 pounds, we can set up a proportion:

8 pounds is to $15 as 10 pounds is to x dollars.

We can cross multiply and solve for x:

8/15 = 10/x

Cross multiplying:

8x = 15 * 10

8x = 150

Dividing both sides by 8:

x = 150/8

x ≈ 18.75

Therefore, someone will have to pay approximately $18.75 for 10 pounds.
