$9
♡ Step-by-step explanation ♡
In the problem, it states that Mira leaves a $1.80 tip. At the same time, it is also mentioned that the tip is 20% of the price of breakfast before it. This means that $1.80 is 20% of the price of breakfast before the tip. In order to figure out the price of breakfast before the tip, we must take the 20% tip and make it into 100%. This 100% will be equivalent to the price of breakfast (before the tip).
To transform 20% into 100%, we must multiply by 5. Therefore, to find the price of breakfast before the tip, we must multiply $1.80 by 5. When we do this, we discover that $1.80*5 is $9. $9 is 100% of the price of breakfast before the tip.
So, the price of breakfast before the tip is $9.
