a) **Amount spent on socks**: $75

**Number of items**: Between 4 – 8 (3 socks and between 1 – 5 shoes)

**Based on the fact that (Amount spent on shoes = Total amount spent – amount spent on socks)**

We know that amount spent on shoes needs to be a whole number, and the amount spent on socks is already a whole number ($75). Therefore, the **Total amount spent** must also be a whole number (Whole number – whole number = whole number).

**Total amount spent = Average cost of items x total number of items**

The average cost of items is $78.60 so we need to find a number less than 8 that when multiplied by $78.60, will give a whole number as the product. The only possible number is 5, so Mr Chua bought 5 items in total. 5 items minus the three socks means he bought **2 pairs of shoes**.

b) **Total amount spent** = $78.60 x 5

= $393

**Amount spent on shoes** = $393 – $75

= $318

**Average price of each pair of shoes** = $318 รท 2

= **$159**
