Shane returned from Las Vegas with $700, which is 75% more than what he had in the beginning of the trip, how kuch money did Shane have in the beginning

Well you take 700 * 1.75 = 1,225

so your answer is $1,225

Find 10% of 700 by removing a 0. 10% of 700 is 70. To get 70%, multiply 70 by 10 to get 490. To get 5% of 700, divide 10% (70) by 2 to get 35. Add 35 to 490 to get 75% of 700 (525).

75% of 700 is 525

Now subtract 525 from 700 and you have your answer

175
