To solve the inequality \(3.5 + 4t \leq 39.5\), start by isolating the term with \(t\). Subtract 3.5 from both sides: \[ 4t \leq 39.5 - 3.5 \] This simplifies to: \[ 4t \leq 36 \] Now, divide both sides by 4: \[ t \leq 9 \] So the solution to the inequality is \(t \leq 9\). Want to test your solution? Pick a value for \(t\) that fits the inequality, such as \(t = 8\). Substitute it back to check: \[ 3.5 + 4(8) = 3.5 + 32 = 35.5 \leq 39.5 \text{ (True)} \] Now try \(t = 10\): \[ 3.5 + 4(10) = 3.5 + 40 = 43.5 \leq 39.5 \text{ (False)} \] You see? \(t = 8\) is correct, while \(t = 10\) doesn't satisfy the inequality—making \(t \leq 9\) the right range!
