(a) The amount of markup is $7.20.
(b) The list price is $23.20.
Step-by-step explanation:
Step 1:
The markup price is the price by which a seller has increased the product's price. The markup price is the difference between the selling price and the buying price.
Darla marked the price up 45%, so we need to determine how much 45% of $16 is.
45% of $16 = 
So she increased the price by $7.20.
Step 2:
The price at which she has listed the bracelet is the sum of the buying price and the markup price.
The list price = The buying cost + the markup cost = $16 + $7.2 = $23.20.

to find ratios that are equivalent to any given ratio you can just divide or multiply both numbers by the same number, like for 2:3, just multiply both numbers by 2 and you'll get 4:6 which is an equivalent ratio

The new parking lot must hold twice as many cars as the previous parking lot. The previous parking lot could hold 56 cars. So this means the new parking lot must hold 2 x 56 = 112 cars
Let y represent the number of cars in each row, and x be the number of total rows in the parking lot. Since the number of cars in each row must be 6 less than the number of rows, we can write the equation as:
y = x - 6 (1)
The product of cars in each row and the number of rows will give the total number of cars. So we can write the equation as:
xy = 112 (2)
Using the above two equations, the civil engineer can find the number of rows he should include in the new parking lot.
Using the value of y from equation 1 to 2, we get:
x(x - 6) = 112 (3)
This equation is only in terms of x, i.e. the number of rows and can be directly solved to find the number of rows that must in new parking lot.
