To find the answer first we will multiply to see how much the books cost. Then we will subtract 50 by the amount of money she has to pay. Then we will check our work to makes sure we are %100 right. Lets do it:-
Lets multiply:-
10 × 2 = 20
So, 10 books cost 20m.
Lets subtract:-
50 - 20 = 30
So she gets 30m in chage.
CHECK OUR WORK:-
30 + 20 = 50
We were RIGHT!!!
So, Coley would receive 30m (B) 30m) in change is she pays with a 50 dollar bill.

Answer:

Step-by-step explanation:
I use 'n' as the unknown value, but you can use any letter you want as the variable.
The product of four and a number would be represented by '4 * n'. The ideal way to write this would be '4n', even though '4 * n' is also correct in value.
The square of the number would be n². Squaring a number is multiplying a number by itself.
The phrase 'difference between...' means subtraction.
Putting it together:
"The difference between the product of 4 and a number and the square of the number" would be:

Hope this helps.
