The toothpaste in Anne's family's bathroom contains 105 grams. Anne's dad uses 3 grams at each brushing, her mom uses 2 grams, Anne and her brother use 1 gram each. Each member of the family brushes their teeth three times a day. How many days will it take for the toothpaste to run out?
Anne and her brother use 1 gram + 1 gram =

2 grams.
Anne's dad uses 3 grams and Anne's mom uses 2 grams so together they use 2 grams + 3 grams + 2 grams = 
<gadget id="calculator">3+2+2</gadget>
<output>7</output>
7 grams/wash.
Each day, the family uses 7 grams/wash * 3 washes/day = 
<gadget id="calculator">7*3</gadget>
<output>21</output>
21 grams.
Using that amount daily, the toothpaste will last 105 grams / 21 grams/day =
