Given :
A holiday meal cost 12.50 a person plus a delivery fee of $30 at we cater.
The same meal cost $15 a person with no fee at Good Eats.
To Find :
When does we cater become the better deal.
Solution :
Let , x is number of order .
Cost at cater , C = 12.5x + 30 .
Cost at Good Eats , G = 15x .
We need to find :
G > C
Therefore, after 12th order cater will be more value for money.
Hence, this is the required solution.
Answer:
Step-by-step explanation:
1,)
3x+y=4 <-Equation 1
2x-y=6 <-Equation 2
Step 1 Eliminating Y Multiply negative both side
-[3x +y = 4 ] -
-3x-y = -4 <-Equation 3
Equation 2 to Equation 3
2x-y=6
-
-3x-y = -4
= 5x = 10
x =2
Substituting X to Equation 1
3x+y=4
3(2) + y =4
6 + y = 4
y = -2
Therefore x =2 and y = -2
Answer:
22
Step-by-step explanation:
Put all the other numbers at the right side of the equation.
-3x + 25 + x + 21 = 2 is the same as -3x + x = -44
-2x = -44
-x = -22
x = 22
