Think About it

How would you check your credit card receipts against a credit card statement?

Practice

Remember to estimate whenever you use your calculator.

You also have a credit card to buy gasoline. Look at the charge receipt.

$\backslash$table$[[$TRU VALUE$],[\backslash$table$[[9700$ Midville Tru Value$],[$Closter$,$ NJ $]]],[$Pump #$0$ Regular Gas$],[$Gallons$,15\mathrm{.}469],[$Price$/$Gal$,$$$4\mathrm{.}029],[$Fuel Sale,$\mathrm{.}3],[$Credit $b$.EE],[***,*****9999],[$Auth$,$AA$],[$Apprvl:$,249936],[\frac{01}{03}\frac{?}{1EE},04$:$25$ PM$]]$

Answer the questions:

What is the date of this charge receipt?

At what time did you purchase the gasoline?

What is the total amount of this charge?
