Joe ran 3 miles yesterday and wanted to run at least 12 miles this week. Write an inequality that can be used to determine the additional number of days joe must run this week if each run is 3 miles. Then solve the inequality.

if you take into consideration the run from yesterday,

Joe needs to run at least three more days

y > = 3

if you don't take into consideration the 3 mile run from yesterday,

The answer is

He needs to run 4 or more days toachieve his goal

y > = 4

Step-by-step explanation:

12 miles as a minimum

that means

let x be the total amount of miles ran

x > = 12

Let y be the number of days in which Joe runs

3*y > = 12

y > = 4
