Johnny has 1050. he spends 55 each week. he wants to stop spending money when he has at least 150 left. how many weeks can he withdraw money from his account?

16 Weeks.

Step-by-step explanation:

1050 - 150 = 900.

900 divided by 55 = 16.3.

Round down, because 3 is less than 5.

Therefore, Johnny can spend $55 each week for 16 weeks and have at least $150 left in his account.

Hope this helps.

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
