Elen deposited $2,500 into a savings account that earns 5% interest per year. her friend's bank offers a 6% annual interest rate. how much more money would ellen's money have earned in one year if she had deposited her money at her friend's bank?

Ellen's money would have earned $25 more than her money at her account

Step-by-step explanation:

* Lets explain how to solve the problem

- The simple Interest Equation (Principal + Interest)  is:

  A = P(1 + rt)  , Where

# A = Total amount (principal + interest)

# P = Principal amount

# r = Rate of Interest per year in decimal r = R/100

# t = Time period involved in months or years

* Lets solve the problem

- Ellen deposited $2,500 into a savings account that earns 5% interest

 per year

- Her friend's bank offers a 6% annual interest rate

* Lets calculate her money after 1 year in each account

# Her account

∵ P = $2500

∵ r = 5/100 = 0.05

∵ t = 1

∵ A = P(1 + rt)

∴ A = 2500(1 + 0.05 × 1) = 2500 (1.05) = 2625

* Her money would be $2625 in one year

# Her friend's account

∵ P = $2500

∵ r = 6/100 = 0.06

∵ t = 1

∵ A = P(1 + rt)

∴ A = 2500(1 + 0.06 × 1) = 2500 (1.06) = 2650

* Her money would be $2650 in one year

∵ 2650 - 2625 = 25

∴ Ellen's money would have earned $25 more than her money at her

  account

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
