Karina starts a savings account with $25. Each month she deposits $15 more into her account. Karina now saved $135. Which equation can be used to determine how many months, m , karina has deposited money into her savings account?
To set this equation up you want to look at key words. It states that "Karina now saved $135" in meaning her total saved. Now it states she STARTED the account with 25 so that would be added to the amount she adds per month (which is $15). The equation can be set up as 15m+25=135. 15m because m stands for every month she added $15, 25 because she started the account with 25 and 135 because that's her total after the several months.
