It will take her 13 weeks. First I subtracted $75.25 from $20 which equals $55.25. Since she plans to save $4.25 each week, I divided that with $55.25 which equals 13.
Take 75.25 subtracted from 20. That is 55 dollars she must save when including her 20 dollars. Take 55 divided by 4.25 and that equals 12.94. So round up. It will take her 13 weeks.
