Harper needs to buy teacher appreciation gifts for her children’s teachers.  Her son has 3 different teachers and her daughter has 4.  If she spent $70 on gifts, how much did each gift cost?
Her son has 3 teachers and her daughter has 4, so together they have 3+4 = <<3+4=7>>7 teachers
Harper has already spent $70 on 7 gifts, so she spent $70/7 = $<<70/7=10>>10 per gift
