The total cost of the hire purchase for the bicycle is $19,145.
The difference between the hire purchase price and the cost price for the bicycle is $2,825.50
The difference as a percentage of cash price 17.31%.
What is total cost?The total cost of the hire purchase is the sum of the deposit and the total monthly instalment.
Total cost of the hire purchase = amount deposited + total instalment paid
Total instalment paid = number of month x payment per month
$1224.50 x 10 = $12,245
Total cost of the hire purchase = $6,900 + $12,245 = $19,145
The difference = cost of hire purchase + cash price
$19,145 - $16 319.50 = $2,825.50
The difference as a percentage of cash price = (2,825.50 / $16,319.50) x 100 = 17.31%

Charlie bought a pair of shorts at the store when they were having a 45 \%45% off sale. If the regular price of the pair of shorts was \$ 24$24, how much did Charlie pay?
Charlie paid $13.2 for the shorts after discount
The regular price of pair of shorts = $24
Discount during the sale on shorts = 45%
Discounts are price reductions that store owners make on items or services that are otherwise priced as marked. This portion of the rebate is typically provided to boost sales or get rid of excess inventory. The price of an item as stated by the manufacturer or seller, without any price reduction, is known as the List price or Marked Price.
Amount of discount = 45% of 24
= 45/100*24
= 10.8
Amount of shorts after discount = Regular price of shorts - Discount on shorts
= 24 - 10.8
Amount after discount = $13.2

At (9, 0), the graph of the equation y = - 2/3 x + 6 intersect the x - axis.
How to create linear equation using two variables?
If an equation is written in the form ax + by + c=0, where a, b, and c are real integers and the coefficients of x and y, i.e., a and b, respectively, are not equal to zero, then it is said to be a linear equation in two variables. Such an equation has a pair of numbers as its solution, one for x and one for y, which further equalizes the two sides of the equation. A specific point on the graph represents the solution of a linear equation in two variables, ax + by = c, where the total of these two values will equal c when the x-coordinate is multiplied by a and the y-coordinate by b. Basically, there are infinitely many solutions to a linear equation with two variables.
The linear equations can be solved using substitution method.
Given, the equation of the graph is : y = (-2/3) x + 6 -(i)
Also, the equation of x-axis is: y = 0 -(ii)
Substituting (ii) in (i), we get,
0 = (-2/3)x + 6 ⇒ (-2/3)x = -6 ⇒ (2/3)x = 6 ⇒ x = 9
Thus, the point where the graph of the equation y = - 2/3 x + 6 intersect the x - axis is (9, 0).

Dawn bought a magazine for $6 and a book for b dollars. She paid for the items with a $20 bill and d dollars bills. Which represents the amount of change that Dawn received?
The change received by Dawn will be equivalent to A = 14 + (d - b).
What is price estimation in mathematics?
Estimation of a price is a reasonable guess of the actual value to make calculations easier and realistic.
Given is Dawn who bought a magazine for $6 and a book for [b] dollars. She paid for the items with a $20 bill and [d] dollars bills.
The total cost of magazines and books purchased by Dawn [C]= $6 + $b
The total money paid for these items [S] = $20 + d
Amount of change received by Dawn will be [A] = S - C
A = 20 + d - (6 + b)
A = 20 + d - 6 - b
A = 14 + (d - b)
Therefore, the change received by Dawn will be equivalent to A = 14 + (d - b).
