At least means greater than or equal to, so that is the symbol we will use. Now, we want the inequality to compare the distance she plans to jog and the amount of time jogged multiplied by the speed, since time times speed equals distance.
Writing this out we get 1.5 ≤ 3.75x
so 1.5 will always be less than or equal to the distance jogged. let me know if there is something you don't understand. But after this just solve for x.
Start by finding out how much he sold on the two days. That will be; Monday: 1/3 x 30= 10 cards Tuesday: 3/2 x 30= 45 cards From the above, you can see that he sold more than 30 cards on Tuesday. But less than 30 on Monday. So the correct answer is H. He sold fewer cards than his goal on Monday and more cards than his goal on Tuesday. Hope I helped. Good luck
