Answer:
I am pretty sure that's true.
Not a 100% sure though.
Step-by-step explanation:
Let p represent the quantity of plates
Let c represent the quantity of cups
Cook 1: 4p + 5c = 25.25
Cook 2: 7p + 3c = 25.50
Use elimination method to solve:
-3(4p + 5c = 25.25) → -12p -15c = -75.75
5(7p + 3c = 25.50) → 35p +15c = 127.50
Add the equations: 23p + 0c = 51.75
Divide by 23 to solve for p: p = 2.25
Answer: the cost of plate is $2.25
Answer:
Step-by-step explanation:
The exponential function is . is the initial value of the function, or the y-value when x=0. In this case, =5. If we enter that into the equation:
Then we can use another point to solve for .
Since anything raised to the power of 1 remains the same, we can continue to solve algebraically.
Now that we have both the and value, we can return to the exponential function and fill in the blanks.
I hope this helps!
It is important to do the
calculations very carefully. Otherwise there is nothing complicated about this
problem.
Let us assume the unknown number = x
Then
40x/100 = 55
40x = 55 * 100
40x = 5500
x = 5500/40
= 550/4
= 137.5
So
55 is 40% of 137.50. I hope the procedure is clear to you and in future
you can solve such problems on your own without requiring any help from
outside.This is the simplest way of solving such
problems.
