80p = 80 cents
£1.50 = $1.50.
(changing the signs, that's it)
So if a small bottle is half the size of a large bottle, and is 80 cents.
Amir buys 4 bottles, so 0.80 * 4 = 320 = $3.20.
Now 4 small bottles is the same as 2 large ones, so if he bought 2 large bottles: $1.50 * 2 = $3.00.
$3.20 - $3.00 = 0.20 cents.
Amir would've saved 0.20
P.S. What is "p" in European money
Gradient is synonymous to slope.
y = 6x + 5 is an example of a slope-intercept form of a straight-line equationl.
The slope-intercept equation is like this:
y = mx + b
where : m = slope ; b = "y-intercept"
y = 6x + 5
6 is the slope
5 is the y-intercept.
Since slope and gradient are synonymous, 6 is the gradient of the above equation.

Answer:
(A) 6%
(B) 57%
(C) 357%
(D) 100%
Step-by-step explanation:
(A) 6 / 100 = 6%
(B) 57 / 100 = 57%
(C) 357 / 100 = 357%
(D) 100 / 100 = 100%
