CPM Homework Help : MC2 Problem 9-9

The lemonade stand at the county fair sells the lemonade at a price of two cups for $$3.00$ . Complete the table below to find what Paula's family will pay to buy lemonade for all $8$ members of the family.

# of Lemonades	Price (in dollars)
$1$
$2$	$3.00$
$3$
$4$
$5$
$6$
$7$
$8$

Hint:

Since 2 cups of lemonade is twice as much as 1 cup of lemonade, to find the price of 1 cup of lemonade, you must half the price of 2 cups of lemonade.

More Help 1:

You can also solve the problem by setting a proportion equation like the one below, then solve for x.

$\frac{\text{2 cups of lemonade}}{\text{3 dollars}} \left( \frac{?}{?} \right) = \frac{\text{1 cup of lemonade}}{x\text{ dollars}}$

More Help 2:

To find the price of any amount of lemonade, in the equation above substitute ''1 cup of lemonade'' with the number of lemonades you are looking for.

# of Lemonades	Price (in dollars)
$1$	$1.50$
$2$	$3.00$
$3$	$4.50$
$4$	$4.50$
$5$	$6.00$
$6$
$7$
$8$
