Thank you for that info. Now, how many 'cutlery' products have the daily hire cost lower than 20?
SELECT count ( product_id )  FROM products_for_hire WHERE product_type_code   =   'Cutlery' AND daily_hire_cost  <  20
count of products = COUNT(product_id); 'cutlery' products refers to product_type_code = 'Cutlery'; daily hire cost lower than 20 refers to daily_hire_cost < 20;
