Question
chris is saving money at a constant rate. suppose he initially has $130 saved, and after 4 months, he has $250 saved.
which of these expresses the rate at which chris is saving?

Based on the information, the amount that he saved monthly will be $30 per month.

Since we are given the information that Chris initially has $130 saved, and after 4 months, he has $250 saved. Therefore, the equation that can be used to calculate his monthly savings goes thus:

= (250 - 130) / 4.

= 120/4

= 30

He saves $30 per month.
