If x is the amount that Tanya paid for each item, then Tony's items would be x-2.25. So:
3x=4(x-2.25)
3x=4x-9
x=9
x-2.25=6.75
Tanya spent $9 on each item; Tony spent $6.75 on each of his items
Answer:
the x axis is 10, its interpretation is actually G, so on a graph instead of X and Y you would have G and T
That would be 950 * 0.62 = 589 British pounds.
