To write the situation as an inequality, we need to express the total value of the coins in terms of dimes and quarters.<br /><br />Given that Yusuf has d dimes and q quarters, we can represent the total value of the coins as:<br /><br />Total value = (d * $0.10) + (q * $0.25)<br /><br />Since Yusuf has at least $2 worth of coins, the total value should be greater than or equal to $2.<br /><br />Therefore, the correct inequality is:<br /><br />C) $0.10d + $0.25q ≥ $2
