Mr. Quick bought a new computer system. The regular price was $1,580, but he got a 15% discount. How much did he actually pay?
Answer:
$1343
Step-by-step explanation:
Mr. Quick bought a new computer system. The regular price was $1,580, but he got a 15% discount. How much did he actually pay?
You need to turn 15% into a decimal.
Move the decimal point to the left 2 spaces.
15 ---> 1.5 ---> 0.15
Now multiply 0.15 by $1,580.
0.15 × $1,580
Which is $237.
Now subtract $1580 - $237.
Which is $1343.
Answer:
$1580*15/100=$237that is discount rate.
$1580-237=$1343 actually pay
Find the selling price.

A local gaming store bought a gaming console for $90. The gaming store sold the console, and the percent markup was 162%. What is the selling price?
The selling price is: $_________
Skip to navigation
Answer:
$145.80
Step-by-step explanation:
The original cost of the product was $90. There was a 162% markup. In order to get the selling price, I like to take away 100 percent and simply add original price+(original price*62%). After taking away 100%, I am left with 62%. I then multiply the original cost ($90) by the remaining percent (62%), getting 55.8. Following the steps that I originally wrote, I now add 90 to 55.8, getting 145.8.

What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
price of food = $137 . 61
Tip = 18%
tax = 6.5%
Now, price after giving tip
=137.61 x 0.18
= 24.7698
and, after tax
=137.61 x 0.065
=8.94465
Hence, final cost of meal = 137.61 + 24.7698 + 8.94465 = $171.35

The Ramirez family has a circular garden with a diameter of 22 feet. They cover the garden with mulch. The cost of mulch is $1.25 per square foot. To the nearest dollar, how much will it cost to cover the garden with mulch. Show your work.
A.$380 B. $475
C. $1.520 D. 1.900
Answer:
b) $475
Step-by-step explanation:
if it has a diameter of 22 feet, that means it has a radius of 11 feet
the formula of the area of a circle is πr². so square the radius and you will get 121, multiply that by π and you get 380
Now we know the area is 380 square feet, so multiply that by $1.25 and the answer is $475
what’s the area of this figure? lol i have no idea helppp
Answer:
285
Step-by-step explanation:
For the top section, we can portion out 20 x 8 = 160.
Next, directly in the middle is a 5 x 5 square = 25.
Finally, we have a right triangle with dimensions 10 x 20 so the area would be 10 x 20 / 2 = 100.
160 + 25 + 100 = 285.
