Answer:
The answer is A. One term of the polynomial has a degree of 3.
Step-by-step explanation:
The quadratic formula can only be used with equations where the highest degree held is 2, so the quadratic formula would not be able to be used in an equation with a degree of 3.
First,multiply both sides by 5 to get rid of the faction:
2(y-40) = 25
then, divide both sides by 2 to get rid of the 2 in the left side:
y-40 = 12.5
then, isolate the y in one side and the other terms on the other.
y = 12.5+40
y = 52.5
For this case we can define the following variables:
x: shirt
y: jeans
We write the following system of equations:
12x + 28y = 3900
8.4x + 35y = 3885
We solve the system of equations:
x = 150
y = 75
Note: see attached image for the solution of the system:
