3-76.

Janelle saw an advertisement for four smoothies selling for $3$. If nine of her friends are coming over and she wants to buy enough smoothies for everyone, how much money will she spend?

First, calculate the cost of one smoothie.

$\frac{3}{4} = 0.75$

$0.75$ per smoothie

Now that you know how much Janelle will need for $1$ smoothie, the next step is to calculate how much money Janelle will need for $10$ smoothies.

$\left(0.75\right)\left(10\right) = ?$
