​Part B

If the price of a digital camera sold in New Mexico is $294.35 including sales tax, what was the list price of the digital camera?

Answer 1

part A

the tax = 16.4 dollars (16 dollars and 40 cents)

`320 * (5.125)/(100) = 16.4`

so the final price is = 320 + 16.4 = 336.4 dollars

part B

x represents list price

`x \: * (5.125)/(100) = 294.35`

so that x = 5743.414634 dollars.

`x \: = (294.35)/( (5.125)/(100) )`
