Answer:
The cost of one donuts is $1.25 and the cost of one cinnamon is $1.75
Step-by-step explanation:
Let
x-----> the cost of one donuts
y ----> the cost of one cinnamon
we know that
-----> equation A
-----> equation B
Solve the system by graphing
Remember that the solution of the system of equations is the intersection point both graphs
using a graphing tool
The solution is the point (1.25,1.75)
see the attached figure
therefore
The cost of one donuts is $1.25 and the cost of one cinnamon is $1.75
If Robert starts from $45 then doubles it every month, as stated his earnings is calculated by the equation y=45 × 2^x. Substitute the value of x with the number of months, 16.
y= $45 × 2^16
y= $2949120
Therefore his earnings is $2949120.
