john is saving money at a constant rate. Suppose he initially has $110 saved and after 2 months he has $160 saved. at what rate is john saving

The rate John is saving is 25. How? You can do 160-110 (to find difference). After this, you will get 50. You can now divide this by 2 (because the problem says two months), which is 25. You can see if this is correct by adding 25 to 110 two times.

110 + 25

= 135

135+25

=160

He saves $25 per month
