Step-by-step explanation:

Marisol has $475. She wants to buy a printer that costs $245.99 but is currently on sale with a 35% discount. Marisol will also have to pay a sales tax of 7%.

First we have to find 35% of 245.99 which is 86.0965. That's how much you saved.

So we have to subtract it from the original cost of the printer.

Now we have to add the sales tax of 7%.

Finally, just subtract the whole (checkout) price (171.086045) from the money she had (475).

How much money will Marisol have left after her purchase?

The exact answer is 303.913955, but it rounds to 303.92 (I'm sure that's what you're looking for).

step-by-step explanation:

payback

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
