Ally's Fitbit tells her she has completed 73% of her goal for number of steps taken
today. If she has taken 5,840 steps, what is Ally's goal for the day

Answers

Answer:

7416.8

Step-by-step explanation:

5,840 x 127%

Since she's 73 percent of the way there, we need to add the last 27 percent as well as put a one in front so it will work.

127%

Because this is not just 7416 steps you should consider rounding it if your teacher asks you to.
