marisol has $475. she wants to buy a printer that costs $245.99 but is currently on sale with a 35%bdiscount. marisol will also have to pay a sales tax of 7%. how much money will marisol have left after her purchase?

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).

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
