Over spring break, Shane works as a lifeguard at his community pool. He works 16.25 hours every week of his 2-week break. He puts 2
5
of his earnings toward a new computer. If he makes $13 per hour, how much money does he save for his computer?

$169

Step-by-step explanation:

Multiply 16.25 x 2 so you can find how many hours he worked

32.50 hours, so now you multiply that by 13 so you know how much money he earned

$422.50, so now you multiply 2/5 x 422.50

Your answer will be 169 dollars

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
