One person saves$75 per week and has $950 at the vacation time. Another one saves$50 per week and has $800 at the vacation time. Let$x be the starting amount and y be the number of weeks.
From the given information,
x+75y=950----1
x+50y=800----2
Solve equations (1) and (2) and obtain the values of x and y as follows.
Subtract equation (2) from (1) and obtain the value of y as shown below.
x+75y-(x+50y)=950-800
x+75y-x-50y=950-800
25y=150
$y=\left(150\right)/\left(25\right)$
y= 6 weeks
now substitute y=6 in equation 1 and obtain the value of c as follows:
x+75y=950
x+75(6)=950
x+450=950
x=950-450
x=$500 Therefore , they start with$500 and save for 6 weeks
Option D is correct
