In 2019, 220 people bought cars from a local dealership and only 60% of the people were satisfied with their purchase. How many (in numerical value) people were dissatisfied with their purchase?

Step 1 ：In 2019, 220 people bought cars from a local dealership and only 60% of the people were satisfied with their purchase.

Step 2 ：We first need to find the number of people who were satisfied with their purchase, which is 60% of the total number of people who bought cars. This can be calculated as \(0.60 \times 220 = 132\).

Step 3 ：Then, we subtract this number from the total number of people who bought cars to find the number of people who were dissatisfied. This can be calculated as \(220 - 132 = 88\).

Step 4 ：So, the number of people who were dissatisfied with their purchase is \(\boxed{88}\).
