Mrs. Hartshorn uses the formula y = -3x + 27 to keep track of how much money she has in her coffee fund each day (she buys one coffee each day). x is the number of days and y is the amount of money in her coffee account. What would the 27 represent in the story?

• What she pays for each coffee

• The rule

• How much money she starts with in her fund

• It means nothing. Mrs. Hartshorn just likes the number 27.
