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.
Would it be something like this:
a. c= # coins
p= points
p=10c
b. p= 3(10c)
The wording is confusing me.
It is confusing, and poorly worded. I wonder how many stars are allowed, if more than one, then
p=3^n *10c where n is the number of stars allowed.
a. To calculate the number of points earned from collecting the coins, you can use the expression:
Number of points from coins = number of coins * points per coin
Since you earn 10 points for every coin you collect, the expression becomes:
Number of points from coins = 10 * number of coins
b. To calculate the total number of points earned after finding the star, you need to incorporate the number of points earned from the coins and the effect of the star into the expression.
Since the star triples your score, you can multiply the number of points earned from the coins by 3. Therefore, the expression for the total number of points earned becomes:
Total number of points = (10 * number of coins) * 3
This can be simplified as:
Total number of points = 30 * number of coins
