Answer:
The number of red pens is 20.
The number of blue pens is 4.
Step-by-step explanation:
We are given that, the ratio of number of red pens to the number of blue pens is 5 : 1.
∴ Let us assume that the number of red pens be 5<em>x</em> and number of blue pens be <em>x</em>.
Total number of pens in the desk drawer = 24
Now, according to question :
Number of red pens + Number of blue pens = 24
⇒5<em>x</em> + <em>x</em> = 24
⇒6<em>x</em> = 24
⇒
So, number of red pens in the drawer = 5<em>x</em> = 5 × 4 = 20
Number of blue pens in the drawer = <em>x</em> = 4
Answer:
B. graph B
Step-by-step explanation:
The graphs of A,B,C and D are attached below.
Let x represent the credit amount and y represent the minimum amount due.
For a bill of less than $100, the entire amount is due. That is for 0 ≤ x < $100, y = x
For a bill of at least $100 but less than $500, the minimum due is $100. That is for $100 ≤ x < $500, y = 100
For a bill of at least $500 but less than $1,000, the minimum due is $300. That is for $500 ≤ x < $1000, y = $300
For a bill of $1,000 or more, the minimum due is $500. But the credit limit is $2000. That is For $1000 ≤ x < $2000, y = $500
The graph that shows the minimum amount due for a credit amount of x is graph B
