The price of an item has been reduced by 40%. The original price was $66. Find the price of the item now.
serious [3.7K]

Answer:

$39.60

Step-by-step explanation:

We are finding 66 - 40%

66 less 40% = 60% of 66

60% of 66 is the price of the item now.

Convert 60% to decimal form by dividing by 100.

60%/100 = 0.60

Multiply the decimal form by 66

66 X 0.6 = 39.60

Since we are dealing with money, keep 2 decimal places, even if the last digit is 0.

The price of the item now is $39.60.

jamie is pedaling due south a 8 mi/hr. his sister, martha, is pedaling due west at 5 mi/hr. after 2 hours, how fast are the two
pashok25 [27]

Both cyclist are moving apart at a speed of 9.434 mi/hr.

<h3>What is velocity?</h3>

Velocity is the direction at which an item is moving and serves as a measure of the rate at which its location is changing as seen from a certain point of view and as measured by a specific unit of time (for example, 60 km/h northbound). In kinematics, the area of classical mechanics that deals with the motion of bodies, velocity is a basic idea. A physical vector quantity called velocity must have both a magnitude and a direction in order to be defined. Speed is the scalar absolute value (magnitude) of velocity; it is a coherent derived unit whose quantity is measured in metres per second (m/s or m/s1) in the SI (metric system).

to find the final cost of the shoes, the $15 coupon can be applied first and then the 20% discount, or the 20% discount can be a
guapka [62]

First apply  20% discount  then applied $15 coupon combination gives better deal.

As given in the question,

Let final cost of the shoes be $100

First apply $15 coupon  then applied 20% discount

100-15=$85

Now,  20% of 85= (20/100) × 85

                          =$17

Final price,  85 - 17 =$68

First apply  20% discount  then applied $15 coupon

Now,  20% of 100= (20/100) × 100

                          =$20

100-20 = $80

Apply coupon $15

Final price, 80 - 15 =$65

Therefore, first apply  20% discount  then applied $15 coupon combination gives better deal.

Sidana [21]

Answer:

X=2

Step-by-step explanation:

-2+6x=12-x

add 2 to both sides

6x=14-x

now add 1x to both sides

7x=14

and finally divide both sides by 7 so you x is left alone

I don't kind fast food sells large burgers for five dollars each and french fries for three dollars each that day they sold six
lesya692 [45]

Answer:

They sold 16 French fries.

Step-by-step explanation:

Let x represent the number of large burgers that they sold on that day.

Let y represent the number of French fries that they sold on that day.

fast food sells large burgers for five dollars each and french fries for three dollars each that day and their total sales was $98.It means that

5x + 3y = 98 - - - - - - - - - - - - - -1

they sold six more french fries than burgers. It means that

y = x + 6

Substituting y = x+ 6 into equation 1, it becomes

5x + 3(x + 6) = 98

5x + 3x + 18 = 98

8x = 98 - 18 = 80

x = 80/8 = 10

y = x + 6 = 10 + 6

y = 16
