Adrianna has 10 pieces of gum to share with her friends. There wasn't enough gum for all her friends, so she went to the store to get 3 more pieces of gum. She gave out gum to 11 friends. How many pieces of gum does Adrianna have now?

Jeff bought 6 pairs of shoes and 4 jerseys for $560. Jerseys cost 1/4 price of one pair of shoes. Find the shoe's price total price.
Let's think: Let X be the shoe price. The jersey's price is 1 / 4 * X. Jeff bought 6 pairs of shoes and 4 jerseys for 6 * X + 4 * (1 / 4X) = $560. Multiplying through the parentheses produces 6X + X = $560. Combining like terms produces 7X = $560. Dividing both sides by 7 produces X = $80, so the shoe price is $80. Since Jeff bought 6 pairs of shoes, he spent 80 * 6 = $480 on shoes.. The answer is: 480.

8 years ago James was twice Janet's age. In 15 years James will turn 37. Susan was born when Janet turned 3. How old will Susan turn in 5 years?
Let's think: James is 37 - 15 = 22 years old. So 8 years ago he was 22 - 8 = 14 years old. That means Janet was 14 / 2 = 7 years old 8 years ago. So Janet is now 7 + 8 = 15 years old. That means Susan is 15 - 3 = 12 years old. So in 5 years she will be 12 + 5 = 17 years old.. The answer is: 17.
