Can someone help? The way the question is worded is confusing me.

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.

Thanks.

I usually do not like giving away full answers, but I believe that a.) would be

y=10(3)x
with y being your total points earned, 30 being your new score from the tripled scores, and x standing for the number of coins you get.
b.) Should be y=30x, the "simplified" form.

a. To write an expression for the number of points you earn from the coins, you need to consider that each coin you collect is worth 10 points. Therefore, the number of coins you collect can be denoted by "c".

The expression for the number of points you earn from the coins is: 10c.

b. To write and simplify an expression for the total number of points you earn, you need to take into account the star you found that triples your score.

Since the score from the coins is represented by 10c, multiplying it by 3 (due to the triple effect of the star) gives you the expression for the total number of points: 3(10c).

To simplify this expression, you can distribute the multiplication by 3: 3 * 10 * c.

This simplifies to: 30c, which represents the total number of points you earn.
