Answer:
The required expression for total number of points you earn is [tex]P=10c+3p[/tex].
Step-by-step explanation:
Consider the provided information.
Let c represents the coin and p represents the points before getting star.
You earn 10 points for every coin you collect in a video game.
[tex]p=10c[/tex]......(1)
You find a star that triples your score.
[tex]star=3p[/tex]
Now the total number of points you earn is(P):
[tex]P=10c+3p[/tex]
Substitute the value of p from equation 1.
[tex]P=10c+3(10c)[/tex]
[tex]P=40c[/tex]
