Answer:

$9 before tip

Step-by-step explanation:

Let's find the price of Mira's breakfast.

Ususally a tip is calculated by a defined percentage, and it means that from the actual price of the breakfast you add to the bill a X% of the price.

This means that if your breakfast price is Y, the tip (T), using a X percentage for tip, can be calculated as:

T=Y*(X/100); notice how 'tip percentage' (X) is divided by 100 to convert a percentage number into a decimal number.

In the given problem, Mira uses a 20% 'percentage tip' which means X=20. Also, Mira leaves a $1.80 'tip' which means T=$1.8.

Now, the problem asks the price of the breakfast (Y), so using the previous equation, we have:

T=Y*(X/100)

$1.80=Y*(20/100)

$1.80*100/20=Y

$9=Y

In conclusion, the price of Mira's breakfast is $9 before tip.

Answer:

$\large\boxed{C)\ \dfrac{3}{4}}$

Step-by-step explanation:

$\text{We know:}\ P(A')=1-P(A)\\\\\text{Therefore}\\\\P(A)-3\cdot P(A')=0\iff P(A)-3\cdot(1-P(A))=0\\\\\text{use the distributive property}\ a(b+c)=ab+ac\\\\P(A)+(-3)(1)+(-3)(-P(A))=0\\\\P(A)-3+3P(A)=0\qquad\text{add 3 from both sides}\\\\P(A)+3P(A)=3\\\\4P(A)=3\qquad\text{divide both sides by 4}\\\\P(A)=\dfrac{3}{4}$
