Answer:
5 weeks
Step-by-step explanation:
Equate Rachel and Roy's savings:
$200 - ($25/wk)w = ($15/wk)w
Combining like terms, we get:
$200 = ($40/wk)w, and so w comes out to 5 weeks.
Answer:
5 weeks
Step-by-step explanation:
200-25x = 15x
we set each equation equal since Rachel has 200 but spends 25 each week we set 200 - 25x (x being the number if weeks) equal to Roy saving $15 per week
200 -25x =15x
+25x +25x add 25x to both sides to isolate the variable
200= 40x
200/40 = 40x/40 divide both sides by 40 to get x by itself
5=x ( previously mentioned x is the number of weeks) therefore they will have either same amount of money after 5 weeks
