Answer

To reach your goal, you must take 4726 or more additional steps.

Work Step by Step

If you want to walk at least 10,000 steps, then your total number of steps must be greater than or equal to 10,000. The total number of steps you will take is the sum of your remaining steps and the steps that you have already taken. Let s represent your remaining steps. $\underbrace{s+5274}\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \underbrace{\geq}\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \underbrace{10000}$ total steps$\ \ $must equal or exceed$\ \ $ your goal Solve the equation. $s+5274\geq10000\longrightarrow$ subtract 5274 from each side $s+5274-5274\geq10000-5274\longrightarrow$ subtract $s\geq4726$
