Answer:
Option B. For every 5 red pens, there are 15 blue pens.
Step-by-step explanation:
The statement expressed the ratio of the red pens to the total as 1 : 4.
This means that for every red pen in the box, there are 4 blue pens.
So, statement A is correct.
Let's skip B an look at other statements as well:
For C, the ratio will be 15 : 60 which translates to 1 : 4. So C is true.
Let's look at D.
This is an interesting one. The problem defines 18 as blue. So it means that 24 - 18 = 6
6 pens will be blue. Again 6 : 24 gives us 1 : 4. So D is true.
B gives us 5 : 24 which is not true.
It takes 4 years for a principal of $25,000 at a simple interest rate of 5% to become 30,000
<em><u>Solution:</u></em>
Given that:
principal = $ 25000
rate of interest = 5 %
Total amount = $ 30000
Number of years = ?
Formula used:
Total amount = principal + Simple interest
30000 = 25000 + Simple interest
Simple interest = 30000 - 25000
Simple Interest = $ 5000
<em><u>The simple interest is given as:</u></em>
Where, "p" is the principal
"n" is the number of years
"r" is the rate of interest
Substituting the values in formula, we get
Thus it takes 4 years for a principal of $25,000 at a simple interest rate of 5% to become 30,000
Answer:
36
Step-by-step explanation:
in 5x+2=17, you solve and get x=3. Then you do 12(3) to get 36.
15/2 is the correct answer
