Linda has $235 in her savings account. She withdrew the same amount each week for 15 weeks. Her balance was then $55. How much money did Linda withdrawal each week?
235 - 15 x = 55
15 x = 235 - 55
15 x = 180
x = 12
Jill had $300 in her savings account before she began depositing an additional $75 each week. Which equation models the relationship between a, the amount Jill has in her account, and w, the number of weeks since she started making deposits?
To find out how much money Linda withdrew each week, we can set up an equation.
Let's assume that Linda withdrew x dollars each week.
In 15 weeks, Linda withdrew a total of 15x dollars.
Since Linda started with $235 in her savings account and ended up with $55, the equation becomes:
235 - 15x = 55
To solve this equation and find the value of x, we need to simplify and isolate x:
235 - 55 = 15x
180 = 15x
Dividing both sides of the equation by 15:
180/15 = 15x/15
12 = x
Therefore, Linda withdrew $12 each week.
