Range is when you subtract the smallest number from the largest number. So X’s range would be 9-0 = 9 & Y’s range would be 8- -12 = 20 I believe.
To find how many pennies Ella has in all, just do 50 * 10. Cross the two zeros out and drop them as part of the answer. Then do 5 * 1 to get 5. When you do this, your answer is 500. Ella has 500 pennies in all.
If Michael has $2 and he spends $1, how much money does he have left? We can figure this out by subtracting $1 from $2. This is obviously equal to $1.
We can use the same idea for this problem. George starts with $23 and spends at least $14. After this, George has 23 - 14 = $9 dollars left. So, George can spend $9 at the max.
We can translate this into math words by saying George can spend less than 9 on glue, so p < 9. So, a. is the correct answer.
