Question

Lucy earned $400 and $550 in interest the last 2 years. Describe the average interest she should earn in each of the next 3 years so that her total earnings over the 5-year period are at least $2300. A) She must average $450 per year. B) She must average $900 per year. C) She must average $1350 per year. D) She must average $1800 per year.

Answer 1

Answer:

If she gets 450 for 3 years plus 400 plus another 500 she would get exactly 2300.  

Step-by-step explanation:

450 x 3 = 1350 + 550 = 1900 + 400 = 2300

(450 x 3) + 550 + 400 = 2300
