TURKEY 0.15xy+20y
GOBBLE 0.20xy+0y
x is the number of texts and y is the number of months
400 texts will need to be sent each month because solving the equation 0.15xy+20y=0.20xy+0y
0.15xy+20y=0.20xy
-0.05xy+20y=0
-0.05xy=-20y
turn -0.05xy into (-y/20)x
(-y/20)x=-20y
((-y/20)x=-20y)/-y/20
x=-20y/-y/20
x=400
TURKEY plan because 0.15(500)y+20y is 95y and 0.20(500)y+0y is 100y, meaning TURKEY would be cheaper.

Suppose the Cost price of iron is 
So, selling price is 
This price must be equal to 
+ VAT
Thus, the cost price is 
Answer:
<em>Improper fraction is 9/4 cups, Mixed number is 2 1/4 cups</em>
<em>9/4 cups of sugar or 2 1/4 cups of sugar</em>
Step-by-step explanation:
36 tsp are in 3/4 of a cup
so you have 1/3 : 36
1/3 is less than a whole teaspoon, so the amount of sugar would be greater than 3/4 cups
1/4 cups of sugar: 1 tsp of butter; or 108 teaspoons of sugar: 1 teaspoon of butter
Hope this helps!

If complex coefficients are allowed, the answer is 3.
If the polynomial must have real coefficients, then each complex root comes as a pair of complex conjugate roots.
Root -5 is real, so that is 1 root, and degree 1.
Root 1 + 4i is complex, so it must come with its complex conjugate, 1 - 4i. This adds 2 roots to the polynomial, and now we're up to degree 3.
Root -4i is also complex. It also must come with its complex conjugate, 4i. That adds two more roots, and the degree is 5.
Answer: The least possible degree is 5 with real coefficients.
