In a video game, you earn 3 points for each jewel, x, you find. You earn 4 points for each star, y, you find. Write an equation that represents the number of jewels, x, and stars,y, you must find to earn 660 points.
Choose the correct equation below.
A. 3x-4y=660
B. 3x+4y=660
C. 4x-3y=660
D. 4x+3y=660
To earn 660 points, you need to earn 3 points for each jewel, x, you find and 4 points for each star, y, you find. Let's say you find x jewels and y stars.
The equation for the total points earned is:
Total points = 3x + 4y
Therefore, the correct equation to represent the number of jewels, x, and stars, y, you must find to earn 660 points is:
3x + 4y = 660
So, the correct equation is B. 3x + 4y = 660.
