Gabriella is selling cakes for a school fundraiser. Customers buy apple and merinque tarts. Castel sold 6 apple cakes and 4 lemon merinque cakes for a total of $ 80. Gabriella sold 6 apple cakes and 5 lemon merinque cakes for a total of $ 94. What is the cost of each merinque cake apple and lemon?

Cost of each apple cake is $4 and Cost of each Lemon merinque cake is $14.

Step-by-step explanation:

Let the cost of each apple cakes be 'x'.

Let the cost of each lemon merinque cake be 'y'.

Now Given:

Castel sold 6 apple cakes and 4 lemon merinque cakes for a total of $ 80.

So we can say that;

6 times cost of each apple cakes plus 4 times cost of each lemon merinque cake is equal to $ 80.

framing in equation form we get;

 ⇒ Equation 1

Also Given:

Gabriella sold 6 apple cakes and 5 lemon merinque cakes for a total of $ 94.

6 times cost of each apple cakes plus 5 times cost of each lemon merinque cake is equal to $ 94.

framing in equation form we get;

 ⇒ Equation 2

Now subtracting equation 1 from equation 2 we get;

Substituting the value of y in equation 1 we get;

Dividing both side by 6 we get;

Hence Cost of each apple cake is $4 and Cost of each Lemon merinque cake is $14.

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

two data sets with the same median will not have the same varaibility
