Question

A bank teller helps two customers. Jerry makes a $20 withdrawal, so his balance changes by-$20. Hank makes a $5 deposit, so his balance changes by $5. Use absolute value to show the size of each transaction. Which transaction involves more money? A. Hank's deposit involves more money, because -20 is greater than 5. B. Jerry's withdrawal involves more money, because 1-20 is less than 51. C. Hank's deposit involves more money, because 1-20 is greater than 51. D. Jerry's withdrawal involves more money, because |-20 is greater than 5 SUBMIT

Answer 1

`\begin{gathered} \text{remember} \\ |a|=\begin{cases}-a,\text{ if a <0} \\ a,\text{ if a }\ge0\end{cases} \\ \\ so,|-20|=20\text{ and} \\ |5|=5;\text{ the size of the withdrawal Jerry made is bigger than the hank's deposit. } \\ Thus,\text{ Jerry's withdrawal involves more money because }|-20|>|5| \end{gathered}`
