Answer:
3500
Step-by-step explanation:
Hello, you need to eliminate fractions in numbers in such questions. So you have to round. If we round the number 45, we get 50. We don't need to round 50 because 50 has no fractions.
1 - 45 - - > 50
2- 50 - - > no change
3- 50 × 50 = 50² = 3500
(Also, if someone sends you an answer with a link when you ask a question, don't click on that link. I came across it and analyzed it, the link is not secure. To stay safe, you can scan unfamiliar links with virustotal.com.)

So look at them

Let b for the number of bicycles, and t for the number of tricycles.
2b+3t=39 ( a bicycle has 2 wheels and a tricycle has 3 wheels)
b=t+2 =>t=b-2
substitute b for t: 2b+3(b-2)=39
2b+3b-6=39
5b=45
b=9
the club buys 9 bicycles and 7 tricycles.
