To solve this, you can use this helpful equation:
= 
Since you now have this equation, you can just plug in.
= 
To find x you would cross multiply, multiply the x with 100 and the 15 with the 20%.
100x = 300
Now to find x you would just divide both sides by 100.
x=3
Answer:
Explanation:
Experimental probability = number of favorable outcomes/number of total outcomes
From the information given,
number of favorable outcomes = 54
number of total outcomes = 120
The experimental probability that the coin will land on heads on the next toss = 54/120
Dividing the numerator and denominator by 6,
The experimental probability that the coin will land on heads on the next toss = 9/20
Day 1 total $60+$15=$75
day 2 total $95+$12=$107
total 2 days = $181
