Answer:
It decreased by 1653$ and he ended up with 4147$
The amount decreased in dollars is $1653 and the amount of money in Brian's account at the end of last year was $4147.
To calculate the amount of money decreased in Brian's investment account, we need to multiply the initial amount of $5800 by the decrease percentage of 28.5%, expressed as a decimal (0.285). 5800 * 0.285 = $1653. This represents the amount decreased in dollars. To find the amount of money in his account at the end of last year, we need to subtract the decrease from the initial amount: 5800 - 1653 = $4147.

Answer:
950- to the nearest ten
900- to the nearest hundred
Step-by-step explanation:
When rounding, the number that we look at is the number to the right of what we are rounding to. When rounding to the nearest ten we look at the number to the right which is in the one's position. In this case that is a 9. In rounding, if the number we are looking at is 1-4 we round down an if the number we are looking at is 5-9 we round up. Since the number is a 9 we round up and the nearest 10 above 49 is 50 so 949 rounded to the nearest 10 is 950. We will repeat this same process when rounding to the hundred. In this case the number to the right of the hundred is the ten which is a 4. since it is between 1-4 we will round down. the nearest hundred below 949 is 900 so 949 rounded to the nearest hundred is 900.
