Kelso is in charge of a bake sale. on each table, t, there will be a platter of 24 cookies and 2 bowls of brownies with b brownies inside. kelso needs an additional 150 cookies to replace what he sells. this situation can be written as the following expression:

24t + (2b)t + 150

how many total sweets are there if there are 7 tables and 12 brownies in each bowl?

Alright he needs 24 cookies per table 
He also need 2 bowls of brownies per table. In where there are 12 brownies per bowl.
Thus, in every table there are also 24 brownies.
He has 7 tables.

 7t (24cookies + 2bowls (12brownies)) + 150 cookies
 7(24 + 24) + 150

 Multiply 7 by 2 24s.

168 + 168 + 150
= 486 
Therefore, Kelso have 318 cookies all in all and 168 pieces brownies or 14 bowls of brownies.Hope this helps!:)

The equation is 24t + 2bt + 150, so check variables and multiply. There's 7 tables, so it's 24(7) + 2(12)(7) + 150. 24 * 7 is 168, 2 * 12 is 24 * 7 which is 168. 168 cookies + 168 brownies + 150 cookies = 486 total sweets.

Iwould say they are complementary because that’s the division of a 90 degree angle and it’s split between the middle of them

The length of what is left would be 1 1/2 feet long.
