Answer:
17 notebooks
Step-by-step explanation:
I) Let's make an equation to represent the problem first:
y = 1.50(x - 0.5)
II) Solve:
25 = 1.50(x - 0.5) (Substitute y with 25)
12.5 = 0.75x − 0.375 (Divide both sides by 1.50)
12.875 = 0.75x (Add 0.375 to both sides)
17 1/6 = x
III) Round down:
Since you can't buy 17 1/6 notebooks, we need to round down our answer.
So, we can only buy 17 notebooks with £25.
