Today in class, we went over some word problems. The word problems that we did, are located on pages 44, 45, and 46 of your purple booklet. In this scribe I will show 3 word problems, and I will explain a little bit of each, so that it makes it easy for you to do.

When you have a word problem, you must answer the word problem with the last sentence from the problem. For example: If the last sentence of a question is "Find the number", then your answer would be "The number is ____". Something like that. There is always numbers in the questions, you just have to find them. Try looking for the variable first, and then the constant. I find it easier for me.

BLUE = The variable in word problem

GREEN = The constant in word problem

RED = The operation (What you're doing to the constant.)

PINK = The answer in word problem

____________________________________

First Question :

Page 44, #15

The sum of eight times a number and fifteen is seven. Find the number.

The number is __

Bring down all of the numbers that you could identify, and this question should look like this.

8n + 15 = 7

The number is -1

REMEMBER - always end your word problem with a sentence solving the question.

For this question, the sentence is right above.

Second Question

Page 45, Letter N

Mo is thinking of a number. Eleven more than one third of the number is -1. Find Mo's number.

n/3 + 11 = -1

Mo's number is -36.

Third Question

Page 45, Letter T

NOTE - Some questions will make it harder for you to find the numbers, but just relax, and take time to find them all.

Mr. Piper's plumbing needed repairs. The plumber charged $98 for parts plus $45 per hour for labor. If the bill totaled $458, how many hours of labor were required?

45h + 98 = 458

8 hours of labor was required.
