Juanita saves $15 each week. Dan has already saved$100 and saves $12 each week. When will Juanita have more money saved than Dan?
The answer is in 7 weeks.
Juanita's saving = 15x Dan's = 100 + 12x
15 x > 100 + 12 x solve for x
3x > 100
x > 33.33 wks so at 34 weeks Juanita will have more money than Dan
