Question 934747: Rita deposited less than $1,000 into two accounts. One account paid 2.5% and the other account paid 2% annual interest. After 1 year, she earned at least $23 in interest from the two combined accounts. If x represents the amount of money Rita deposited at 2.5% and y represents the amount of money she deposited at 2%, which system of inequalities can be used to find the values of x and y?

x = amount invested at 2.5%
y = amount invested at 2.0%
---
x + y = 1000
0.025x + 0.020y = 23
---
put the system of linear equations into standard form
---
x + y = 1000
0.025x + 0.020y = 23
