You begin with $25 in a savings account and $50 in the checking account. each week you deposit $5 into savings and $10 into checking. after how many weeks is the amount in checking twice the amount in savings? write and solve an equation.

To find the answer to this question, you simple have to find the answer to the following sequence. 10*5=50+50=100 5*5=25+25=50 5 weeks

You begin with:

$25 in a savings account $50 in the checking account.

After first week:

$25+$5=$30 in a savings account $50+$10=$60  in the checking account.

After second week:

$30+$5=$35 in a savings account $60+$10=$70  in the checking account.

After third week:

$35+$5=$40 in a savings account $70+$10=$80  in the checking account.

After fourth week:

$40+$5=$45 in a savings account $80+$10=$90  in the checking account.

After fifth week:

$45+$5=$50 in a savings account $90+$10=$100  in the checking account.

You can see that after fifth week the amount in checking is twice the amount in savings.

Let x be the number of weeks, then the equation is:

25+5x=50,

5x=50-25,

5x=25,

x=25:5,

x=5.

after 5th week.
