Answer 1

Answer: 1.85€, 0.5€

Step-by-step explanation:

Given

Peter bought 5 pens and 8 pencils which costs 13.25€

The pencil is 1.35€ cheaper than the pen

Suppose the price of a pen and pencil is x and y

So, we can write

$\Rightarrow 5x+8y=13.25\quad \ldots(i)\\\Rightarrow x-y=1.35\quad \ldots(ii)$

Solving the above equations, we get

$x=1.85,y=0.5$

Therefore, the price of a pen and pencil are 1.85€ and 0.5€.
