Lee bought three books for a total of $£14.50$. The individual prices of the books are $£3.99$, $£5.99$, and $£6.99$. We need to find how much money Lee saved compared to the full price of the books. Also, we need to find the missing number in the statement "... is 20 more than 237".

1. Problem Description

Lee bought three books for a total of $£14.50$. The individual prices of the books are $£3.99$, $£5.99$, and $£6.99$. We need to find how much money Lee saved compared to the full price of the books. Also, we need to find the missing number in the statement "... is 20 more than 237".

2. Solution Steps

First, let's calculate the full price of the books by adding their individual prices:

$Full Price = £3.99 + £5.99 + £6.99$

$Full Price = £16.97$

Next, we subtract the sale price from the full price to find the amount saved:

$Savings = Full Price - Sale Price$

$Savings = £16.97 - £14.50$

$Savings = £2.47$

Now, we solve the second part of the problem: "... is 20 more than 237". Let the missing number be $x$.

$x = 237 + 20$

$x = 257$

3. Final Answer

Lee saved £2.
