Illustrative Math

A new bicycle sells for $300. It is on sale for \frac{1}{4} off the regular price. Select all the expressions that represent the sale price of the bicycle in dollars.

300*\frac{1}{4}

300*\frac{3}{4}

300*(1-\frac{1}{4})

300-\frac{1}{4}*300

Purchase price = year 0

After 1 year...

Just the value at n=0

So what does that mean in plain English?

Number of folds...

Must address the 100 meaning and the 1/2 meaning.

Expression means no = sign. No need to find the value.

So April was month 1, that makes May month 2. Adjust your expression.

You definitely want to exponents now...

Lin has 13 mystery novels. Each month, she gets 2 more. Select all expressions that represent the total number of Lin's mystery novels after 3 months.

Should be in the format of:

#6 answer is used here...

So after 5 years...must round to nearest cent.

So our starting number is:

After 1 hour..

After 2 hours...

After 3 hours...

After 4 hours...

After 5 hours...

Just the difference...

an expression using n...

So is 65 a growth factor, rate of change, or neither
