Question

James Augustine wants to deposit the following into his savings account: 12 one-dollar bills, 4 five-dollarbills, 10 quarters, 12 dimes, 40 pennies, a check for $132.51, and a check for $32.12. He wants to receive 2twenty-dollar bills in cash. How much will he deposit?

Answer 1

`\begin{gathered} 12\text{ one dollar bills = 12 }*1dollar=12\text{ }dollars \\ 4\text{ five-dollar bills = 4}*5=20\text{ }dollars \\ 10\text{ quarters of dollar = 10}*(1)/(4)=2.50\text{ dollars } \\ 12\text{ dimes = 12}*0.1\text{ dollar = 1.20 dollars } \\ 40\text{ pennies = 0.40 dollars, then } \\ 132.51\text{ dollars } \\ 32.12\text{ dollars } \end{gathered}`

Adding we have

`12+20+2.50+1.20+0.40+132.51+32.12=200.73`

But he wants to receive 2 twenty-dollar bills in cash, that is

`2*20\text{ dollars = 40 dollars }`

So we will subtract from 200.73, we have

`\begin{gathered} 200.73-40 \\ =160.73 \end{gathered}`

Hence the answer is $160.73
