Answer:
2 erasers cost <u><em>$1.20</em></u>
Step-by-step explanation:
Nigel bought 10 pencils and 5 erasers for $8.
We can write this algebraically:
10p + 5e = 8
We know that the price of 2 pencils is $1. That is $0.50/Pencil.
So, p = $0.50. Now we can plug that into out equation and find the price of one eraser:
10(0.50) + 5e = 8
5 + 5e = 8
5e = 3
e = $0.60
Now, we have the price of one eraser,<em> </em><u><em>$0.60</em></u>, and we can multiply this by 2 to find the price of 2 erasers, which equates to <u><em>$1.20</em></u>.
So given the values above, if 4 pounds costs $16, this would mean that per dollar or $1 is 0.25 pounds. And the equivalent of 0.25 pounds to ounces is 4. Therefore, the given rates above are equivalent. Hope this answers your question. Have a great day!
This can be written as:

"No greater than" does not necessarily mean less than, but it just means it cannot go over. So equal to or less than.
"The difference of a number and 2" can be represented as "n - 2"
If you were to solve this inequality, you would end up getting:
