2-69.

Janelle and three of her friends bought four smoothies of equal cost for a total of $\3$. If she purchases the same smoothies on another day for herself and nine of her friends, how much money will she spend? Homework Help ✎

First, calculate the cost of one 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.

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

$\0.75$ per smoothie

$(\0.75)(10)=?$
