Final answer:

To find out how much money Amy had initially, we can set up an equation using the given information. By solving the equation, we find that Amy initially had 200p.

Step-by-step explanation:

To solve this problem, we can set up an equation using the information given. Let's say that Amy initially had x amount of money. According to the question, she spends 30% of her money on a book and saves 60%. So, she is left with 100% - 30% - 60% = 10% of her money, which is equal to 20p. We can set up the equation:

10% of x = 20p

To solve for x, we can write the equation as:

0.1x = 20p

To isolate x, we divide both sides of the equation by 0.1:

x = 20p / 0.1

x = 200p

Therefore, Amy initially had 200p.
