Hay nueve profesores y dos secretarias. Is my math solution correct?

Question

From Qfreed in response to a previous post: I hope that the original problem explained that your list of teachers is mutually exclusive (your list adds up to 9 teachers). I am supposing that the 1 teacher that needs 4 dictionary, 1 clock and 2 notebooks, cannot also be one of the 3 teachers that needs.....

For the homework, we were given the following. Nothing was said about mutually exclusive but I have done my calculation with this assumption. I will find out the professor's answer next week!

Given: Hay nueve profesores y dos secretarias. Cada profesor necesita una mesa. Tres profesores necesitan un cuaderno y diez bolígrafos cada uno. Tres profesores necesitan ocho lápices y una silla cada uno. Dos profesores necesitan veinticinco cuadernos y una pizarra cada uno. Un profesor necesita cuatro diccionarios, un reloj y dos cuadernos. Cada secretaria necesita quince bolígrafos, una computadora, veinte lápices, quince relojes y una mochila.

Math Problem: De compras (shopping). You are responsible for buying supplies for an academic department. Figure out how many of the following items you need to order. Be sure to show your computations

Example/Model Modelo: 9 mesas (9 * 1) = 9

My Solution: cuadernos = 3(1) + 2(25) + 1(2) = 3 + 50 + 2 = 55 notebooks

computadoras = 2(1) = 2 computers

lápices = 3(8) + 2(20) = 24 + 40 = 64 pencils

pizarras = 2(1) = 2 black boards

mochilas = 2(1) = 2 backpacks

bolígrafos = 3 (10) + 2(15) = 30 + 30 = 60 pens

diccionarios = 1(4) = 4 dictionaries

relojes = 1(1) + 2(15) = 1 + 30 = 31 clocks

Sorry for the length of this! And I hope you enjoyed doing this exercise with me! Hopefully Jason sees this and any other math teachers!

Answer 1

I think you´re forgetting the chairs.

I guess the 3 professors stand all day! I looked for them, too, and no questions was asked in the homework! - bandit51jd, Jan 30, 2011

Answer 2

I'm not sure if anyone is following this, but last night's class was cancelled due to the winter storm that is hitting central Illinois (and other parts of the world). Today's classes are canclled, too, and it's not looking good out there! I figure if luz-72 and I have the same answers the professor had better come up with the same! I'll post the professor's solution whenever we go to class again.

great bandit, I was sure curious, still am to what he said!! :) - 00494d19, Feb 1, 2011

...thank you for the update, bandit:)...looking forward to your professor's solution:) - luz_72, Feb 2, 2011

The entire community college closed today, too! Next class is Monday the 7th! - bandit51jd, Feb 2, 2011

Answer 3

I'm getting the same result, bandit

Wonderful, I'll find out on Monday what the answers are and will post them on Tuesday! - bandit51jd, Jan 30, 2011
