In mathematical notation, ∑ means summation. So wherever you see the symbol, you have to sum over all elements in the set. Let's solve the question.
a. ∑m means, to sum all elements in the set m: ∑m = 12 + 15 + 20 + 30 = 77
b. ∑ means to sum all elements in the set f as the square of the elements f =
c. ∑mf means to sum all elements as the product of the elements of m and f = (12×5) + (15×9) + (2010) + (30×16) = 875
d. ∑ means to sum all elements as the product of the square of m and f =
Answer:
125,000,000
Step-by-step explanation:
In percentage,
Media + Sales = 3 + 17 = 20%
Let total budget be "t", so we can say:
20% of total budget is 25,000,000
"of" means "multiplication" and "is" means "equal to", so we can convert word equation to algebraic equation. Shown below:
20% * t = 25,000,000
20% = 20/100 = 0.2
Thus, the final equation is:
0.2t = 25,000,000
Solving for t, we get:
The total budget is (125 million) = 125,000,000
