PART A. If sales tax is 8% in orange county what is the sales tax that he will be round to the nearest sent
part to be

Part B what is the total price?

Explain how you got your answer.

Step-by-step explanation:

Meal cost=$15.75

tip=15%

   =  (15*15.75) /100

=236.25/100

  =2.235$=2.24 will give as tip

Cost of shoes=80$

Discount=50%

coupon discount=10%

Total discount=50%+10%=60%

Final price of shoes=?

( 60*80)/100

4800/100

48

60% of 80 is 48 .

pricec  that lyia paid=total price-dicount

         =80-48

         =32$

Xbox=$350

NBA=$45

total=395$

sales tax=8%

(8*395)/100

3160/100

31.6=31.60$

For total price=31.60+395=426.6$

1.) $2.36  

2.) $36

3.) a) $31.60

3.) b) $426.60

Step-by-step explanation:

1.) To begin we need to convert 15% to a decimal. To do this we can move the decimal point 2 spaces to the left. This gives us 15% -> 0.15

Then we multiply this number (0.15) by the total mean cost.

15.75 · 0.15 = 2.36

This means that a 15% tip on a $15.75 meal would add $2.36 to the total cost.

2.) To begin we need to find what 50% of 80 is. This is simple because 50% is half of the original price. We can also move the decimal place over 2 numbers to the left to get 0.50 and multiply this by the original price.

80 · 0.50 = 40         OR...        80 ÷ 2 = 40

Now the problems says that Lyla has an extra 10% off from that discounted price that we just figured out (40). We move the decimal place 2 numbers to the left again and multiply by 40.

40 · 0.10 = 4

Finally we subtract our 10% discount (which is $4) from our new original price ($40).      

40-4 = 36

3.) a.) 350 + 45 = $395 ( this is the price of both items before tax).

To find the extra cost of the 8% tax we move the decimal over to the left 2 places. 8% -> 0.08

We can then multiply of cost and tax.

395 · 0.08 = 31.60 (this means that there is a $31.60 tax on this purchase).

3.) b.) For the total price we add the tax we just found and the original cost of the 2 items.

$31.60 + $395 = $426.60
