Christiana and Marlena opened their first savings accounts on the same day. Christiana opened her account with $40 and plans to deposit $10 every month. Marlena opened her account with $25 and plans to deposit $15 every month. After how many months will their two accounts have the same amount of money? What will that amount be?

It will take 3 months for their accounts to have the same amount and the amount would be $70.

Step-by-step explanation:

Christina: Her initial amount is $40 and each month she adds $10, so the equation would be 40+10x.

Marlena: Her initial amount is $25 and she add $15 each month, so the equation would be 25+15x

Plug both of these equations into a graphing calculator (Desmos) and look for both lines intersect.

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
