You must be at least 48 inches tall to ride an amusement park ride, and your little sister is 30 inches tall. How many inches/must she grow before she may ride the ride?
You need no more than 3,000 calories in a day. You consumed 840 calories at breakfast and 1,150 calories at lunch. How many calories c can you eat for dinner?

18 inches is the answer to the first question because you must be 48 but you are only 30 now, you must grow 18 (4830)
1,010 is the answer to the second question, 840+1,150=1990 but you can only eat 3,0001,990 now which is 1,010

thank you!

48inches by 30inches

A children's ride at an amusement park has a rule that a person must be shorter than 4 feet tall to ride it. Create an inequality that shows the height, x, in feet, a person must be to go on this ride.
