For the word problems below, assume you have animalA and animalB defined in your code.

Directions: Define a function called kilos, which consumes a Row of the animals table and divides the pounds column by 2.2 to compute the animal’s weight in kilograms.

Contract and Purpose Statement

Every contract has three parts…​

# _____::(r :: Row)->______

# ______________________________________________________________

Examples

Write some examples, then circle and label what changes…​

examples:

_______ (_________)is _______________________

_______ (_________)is _______________________

end

Definition

Write the definition, giving variable names to all your input values…​

fun _____(_):

___________________

end

Directions: Define a function called smart-dot, which consumes a Row of the animals table and computes the image of a solid red circle using the animal’s pounds as the radius.

Contract and Purpose Statement

Every contract has three parts…​

# _________::____________________->Image

# Consumes an animal, and computes a solid red circle using the weight in pounds as the radius

Examples

Write some examples, then circle and label what changes…​

examples:

__smart-dot ("animalA") _________is _________________________________________

___________ (_________) _________is _________________________________________

end

Definition

Write the definition, giving variable names to all your input values…​

fun _________(_):

_____________________________________
