Fara started collecting stamps in January. In each month from February to May, she collected 30 stamps more than the month before. She saved a total of 750 stamps from January to May. How many stamps did she collect in January?
Solution
5 units + 10 groups of 30 ---- 750
5 units + 300 ---- 750
5 units ---- 750 – 300 = 450
1 unit ---- 450 divided by 5 = 90
Answer: 90 stamps
