The percent of markup is 20%
Step-by-step explanation:
Selling price of the drink = $1.50
Cost of the drink last year = $1.25
Percent of markup = (selling price - cost) (100)/cost
Percent of markup = (1.50 - 1.25)(100) /1.25
= 0.25(100) /1.25
= 25/1.25
= 20%
The percent of markup is 20%
The answer is f(x)= 2,000,000 (1.02)^x.
Answer:
The correct option is (a) 3759.
Step-by-step explanation:
The complete question is:
The natural resources of an island limit the growth of the population. The population of the island is given by the logistic equation
where t is the number of years after 1980. What is the limiting value of the population?
(a) 3759
(b) 23
(c) 761
(d) 1017
Solution:
The limiting value is the value of the function P (t) for <em>t</em> → ∞.
As <em>t</em> → ∞, the expression
→ 0.
Thus, making the denominator of P (t) 1.
So, the limiting value of the population is, 3759.
Thus, the correct option is (a) 3759.
Answer:
k = 
Step-by-step explanation:
Expand.
11k - 8 = 11 + 8k + 72
Simplify 11 + 8k + 72 to 8k + 83.
11k - 8 = 8k + 83
Add 8 to both sides.
11k + 8k + 83 + 8
Simplify 8k + 83 + 8 to 8k + 91.
11k = 8k + 91
Subtract 8k from both sides.
11k - 8k = 91
Simplify 11k - 8k to 3k.
3k = 91
Divide both sides by 3.
k = 
Answer:

Step-by-step explanation:
Let the time for which i bike is = x hours
Let the distance traveled in x hours = y miles
Ratio of distance and time will be = x : y
I travel 11.2 miles in 1.4 hours then the ratio of time and the distance traveled will be 1.4 : 11.2 Or 14 : 112
then the ratio of distance and time will be same in both the cases
So equation will be


Therefore, equation representing the proportional relationship will be
