Answer: 0.15p+1.59n ≤ 5.00
Step-by-step explanation:
Given: A pencil costs $0.15, and a The notebook costs $1.59.
Let p = Number of pencils.
n = Number of notebooks.
Total cost of pencil and notebook = 0.15p+1.59n
Since Mayumi has $5.00.
So, Total cost of pencil and notebook ≤ $5.00
⇒ 0.15p+1.59n ≤ 5.00
Hence, the required inequality: 0.15p+1.59n ≤ 5.00
I think B is the correct answer. But I’m not sure 100%
Let the two consecutive even numbers be x and x+2
According to the question,
x+x+2=22
or,2x+2=22
or,2x=22-2
or,2x=20
or,x=20/2
therefore x=10
now x+2 = 10 + 2 = 12
Therefore the numbers are 10 and 12

1. 3(p-q)
2. 4(2m+3n+4r)
3. 2x(2x-3y)
