Five children in the Woods family have decided to purchase an anniversary gift for their parents. They estimate the price of the gift to be $170. Each person has already contributed $10. If they have eight weeks to raise the rest of the money, how much will each child have to contribute each week?
5 children = > $50
$170 - $50 = $120
8 weeks $120
1 week = > $15
5 children 15/5 = 3$
each child must contribute $3 per week .
