Complete all steps of the Design Recipe to solve both of the problems below. We’ve provided a start to the first problem as a model.

Define a function called ounces, which consumes a Row of the animals table and computes the number of ounces the animal weighs (1 lb = 16oz). HINT: use predefined rows like cat-row to make your examples easier!

Contract and Purpose Statement

Every contract has three parts…​

ounces::Row->Number

_

Examples

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

examples:

ounces (dog-row) is 16 * dog-row["pounds"]

ounces (cat-row) is 16 * cat-row["pounds"]

end

Definition

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

fun ______(_):

________________

end

Define a function called grams, which consumes a Row of the animals table and computes the weight of the animal in grams (1 lb is roughly 454 grams). HINT: use predefined rows like cat-row to make your examples easier!
