# Bake Sale

## Solution

They had 5 cookies left.

## Explanation

**One Way to Solve**

Tammy sold 32 cookies.

Nick sold 5 more than Tammy.

32 + 5 = 37

Cara sold 10 fewer than Tammy.

32 − 10 = 22

Add the number of cookies each person sold to find out how many they sold altogether.

32 | the number of cookies Tammy sold | |

37 | the number of cookies Nick sold | |

+ 22 |
the number of cookies Cara sold | |

91 | the total number of cookies sold |

Subtract.

96 | the number of cookies they had to sell | |

− 91 |
the number of cookies they sold | |

5 | the number of cookies they had left |

If you use the hundred chart, assign each person a different color.
