Question

Ill be concise:60% of people in survey had income greater than 25k, 40% under 25k. Further, same survey, 70% have exactly 2 cars, while 30% have a different number than 2. The probability that the residents own 2 cars IF income is over 25k is 80%.

what is the probability of a household have exactly 2 cars AND an income UNDER 25k?
i get the answer 28%. the right answer is 22%.
I don't know how to incorporate the last 80% chance bit of the setup part. please help
