Answer
Find the cost of the meals before the tip.
To prove
As given
Emily takes her friend Darren out to eat for his birthday.
She pays a total of $45, which includes a 20% tip.
20% is written in the decimal form
[tex]= \frac{20}{100}[/tex]
= 0.20
Cost of the tip = 0.20 × 45
= $ 9
Thus
Cost of the meals before the tip = Cost of the meal with tip - tip cost
= $45 - $9
= $ 36
Therefore the cost of the meals before the tip is $36 .
Answer: $37.50
Step-by-step explanation:
Let c= cost before the tip
*Turn 20% into a decimal
c+ 0.20c=45
1.20c=45
45/1.20=37.50
That is the cost before the meal.
