Sol sells candy bars to raise money for her softball team. On the first day, she sells ten candy bars and sells four more candy bars than she sold the previous day each day afterward. If she sells six days a week and each candy bar costs 10 cents, how much will she earn in a week in dollars?
Sol will sell 10 + 4 = <<10+4=14>>14 candies on the second day.
She will sell 14 + 4 = <<14+4=18>>18 candies on the third day.
She will sell 18 + 4 = <<18+4=22>>22 candies on the fourth day.
She will sell 22 + 4 = <<22+4=26>>26 candies on the fifth day.
She will sell 26 + 4 = <<26+4=30>>30 candies on the sixth day.
She will sell a total of 10 + 14 + 18 + 22 + 26 + 30 = <<10+14+18+22+26+30=120>>120 candies in a week.
Hence, she will earn 120 x 10 = <<120*10=1200>>1200 cents.
Since 1 dollar is equal to 100 cents, then Sol will earn 1200/100 = $<<1200/100=12>>12
