Question

Tony makes a table to use as a quick reference guide:

Cookies baked (y) is a function of number of batches (x).

Use the table tool to answer the question.

How many cookies will Tony have if he bakes 10 batches more than the maximum number of batches in the table?

Enter the correct answer. ​

Answer 1

Tony will have 486 cookies if he bakes 10 batches more.

Take two points from table: (8, 234), (9, 252)

Find slope:

`slope: (y_2 - y_1)/(x_2- x_1) \ \ where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points`

`\rightarrow slope \ (m) : (252-234)/(9-8) = 18`

This determines that one batch of cookies has 18 cookies.

So, if he bakes 10 more batches:

(10 × 18) = 180 cookies

Total cookies he then will have:

306 cookies + 180 cookies = 486 cookies.
