Math question: If the number 7545 is rounded to the nearest hundred, what is the new value?

Rounding 7545 to the nearest hundred yields 7600. When rounding to the nearest hundred, we look at the tens digit (4 in this case) to determine whether to round up or down. Since 4 is closer to 0 than 10, we round down to 7500. Finally, we adjust the number to the next hundred, resulting in 7600.

Math question: If a number is increased by 75% and then decreased by 20%, what is the final value of the number?

To find the final value, we start with the original number 7545. Increasing it by 75%, we multiply 7545 by 1.75, obtaining 13,206.25. Next, we decrease this result by 20% by multiplying it by 0.8, giving us 10,565.00. Therefore, the final value of the number 7545, after the increase and decrease, is 10,565.
