Let rs.5 denominations be x , then rs 10 denominations will be 90-x
then total amount 5x + 10(90-x) which is rs.500
5x + 10(90-x) = 500
900 - 5x = 500
400 = 5x
therefore x = 80
therefore no. of rs.5 is 80
no. of rs.10 is 90-x = 90-80 = 10
The types of items that cost less than $3.75 per item are Paperbacks and notebooks.
<h3>How do we determine the price of a unit item in a word problem?</h3>
The price of a unit item can be determined by dividing the total price by the number of units sold.
Given that:
Paperbacks sold 3 units for $10.65;
- 1 unit will be sold for = $10.65/3 = $3.55
Notebooks sold 4 units for $14.36;
- 1 unit will be sold for = $14.36/4 = $3.59
Puzzles sold 3 units for $11.85;
- 1 unit will be sold for = $11.85/3 = $3.95
Picture frame sold 4 units for $15.20;
- 1 unit will be sold for = $15.20/4 = $3.80
Therefore, from the above calculations, we can conclude that the types of items that cost less than $3.75 per item are Paperbacks and notebooks.

#SPJ1
In a parallelogram, the diagonals bisect each other.
That being the case,
6x = 72
x = 12
AND
x-5 = y
72 -5 = 67
y=67
x = 72
and the diagonals measure
144 and 134
Step-by-step explanation:
there's no picture???
1) you can expand the brackets, simplify, set the equation = 0 and then do a double bracket factorisation.
2)
therefore Josh's solution is wrong asx = 7 and x= -1
