Answer:
Anton played a total of 39 games.
Step-by-step explanation:
If you want to calculate the amount of games played, you must first subtract the membership fee of 895 to get 1170. As you are charged $30 for each game, you must divide by thirty.
If you are fond of graphing, know this equation can also be expressed in slope-intercept form (y = mx + b) as y = 30x + 895, with x being the number of games played and the y-intercept (895) being your initial cost.
Let x be the number of coins at $10
The number of coins at $20 are 53-x
Hence the equation:
10.x + 20(53-x) = 750
Solve for x & you will find x =31 (at $10/each) and the others, 22 at $20 each)
