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?

135=15m+25 OR 15m+25=135

Step-by-step explanation:

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.

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
