Solve the problem on page 11 of 17 below.
A player starts with 500 tokens in a game and uses 10 tokens in each turn. The expression 500−10t represents the number of tokens remaining after t turns. How many tokens are remaining after 15 turns?
To find the number of tokens remaining after 15 turns, we substitute t = 15 into the expression 500−10t:
500 - 10(15)
500 - 150
= 350
Therefore, after 15 turns, there will be 350 tokens remaining.
