16. Marcia is saving $8 per week
for a new bike.
She has $28 saved already.
This is the equation that could
be used to find
how many more weeks
she needs
to save in order to have a
total of $100.
40. A drawer contains 6 pens.
One of them is out of ink,
but the other 5 work.
What is the probability
of picking two pens
that work if the first pen
picked is NOT
replaced after it is picked?
