A cell phone that regular costs $780 is on sale for 15% off. What is the total cost of the phone if you have to pay 5.5% sales t
Alex_Xolod [135]

Answer:

$700

Step-by-step explanation:

Step one:

Given data

Regular cost of cell phone= $780

discount = 15%

tax = 5.5%

Step two

Let us compute the discounted amount

= 15/100*780

=0.15*780

=$117

hence the selling price is

=780-117

=$663

Also, the tax-deductible is

=5.5/100*663

=0.055*663

=$36.465

The total cost of the phone will be

=663+36.465

=699.465

=$700 to the nearest cent

You decide you will buy a stock only if it shows an overall increase over the next 30 days. The first 10 days it has an average
stealth61 [152]
First 10 days...average daily increase of 0.30 .....total increase for those 10 days is (0.30 x 10) = $ 3

next days.....average daily increase of 0.45....total is (0.45 x 10) = 4.50

last ten days...average daily increase of 0.25.....total is (0.25 x 10) = 2.50

it changed all together : 3 + 4.5 + 2.5 = + 10

It is showing an overall increase, so I guess u should buy it.
