Bart bought a digital camera with a list price of $219 from an online store offering a 6 percent discount. he needs to pay $7.50 for shipping. what was bart's total cost? $205.86 $211.50 $213.36

One way to calculate the price of the digital camera after discount is to subtract 6% from 100% (obtaining 94%) and then taking the appropriate percentage of the full list price:  (1.00-0.06)($219) = $205.86.

Now add the $7.50 shipping cost to    $205.86:  $205.86 + $7.50 = $213.36
(answer)

1.17+3.99a. you combine the terms with a to create 3.99 and the 1.17 stays because it has no like terms or a variable
