Can someone help me figure this out?
You earn 10 points for every coin you collect in a video game. Then you find a star that triples your score.
a. Write an expression for the number of points you earn from the coins.
b. Write and simplify an expression for the total number of points you earn.
Triples the number of points of one coin or for all the previous coins?
Certainly! I can help you with that.
a. To write an expression for the number of points you earn from the coins, we need to consider that you earn 10 points for every coin you collect. Let's say the number of coins you collect is denoted by "c". Therefore, the expression for the number of points earned from the coins would be "10c".
b. Now, let's write and simplify an expression for the total number of points you earn. We know that in addition to the points earned from the coins, you also find a star that triples your score. So we need to multiply the points earned from the coins by 3. The simplified expression for the total number of points you earn would be "3 * 10c" or simply "30c".
To summarize:
a. The expression for the number of points earned from the coins is 10c.
b. The simplified expression for the total number of points earned is 30c.
