After 3 years she will have earned $101.25 in interest and her total amount of money will be $851.25
Step-by-step explanation:
In order to find the amount of money earned you first have to multiply 4.5% in decimal form by 750. From this you get 33.75. This is the amount of interest earned in one year.
Then you have to multiply the interest of one year by 3, since she will be keeping the money in the account for a 3 year minimum. This equals 101.25. $101.25 the money she will have earned over interest after 3 years.
To get the total amount of money she will have earned in her account you have to add 101.25 to 750 which has a sum of $851.25.
When the polynomial has more than one variable you have to sum the exponents of the variables for every monomial. The largest sum is the order of the polynomial.
Here:
momomial sum of the exponents 8x^3y^2 3 + 2 = 5 -10xy 1 + 1 = 2 4x^2y^2 2 + 2 = 4
