How can expressions be written and evaluated to solve for unknowns in the real world?

Writing expressions requires figuring out which quantity in a situation is unknown, and define a variable to represent that quantitiy.

We look for words in the problem that will help us out what kind of operation to use in a given situation.

Example:

Donna bought 5 chocolate bars, and then ate some. Write an expression to represent how many chocolate bars Donna has left.

If we let the variable c represent the number of chocolates Donna has eaten, then we can write the expression on how many bars Donna has left as: 5 - c

Answer:

About 0.3 billion dollars

Step-by-step explanation:

5 years = 60 months.

The 150 of the first month will be 150*1.07^60 in 5 years.

The 150 of the second month will be 150*1.07^59 in 5 years.

The 150 of the third month will be 150*1.07^58 in 5 years.

And so forth.

So we sum that up:

( sum_(n=1)^(60) 150×1.07^n)

And multiply with

× 1.07^(5×23)

to account for the increase in value in the following 23 years.
