Answer:
5 pencils will cost €0.7
Step-by-step explanation:
We can set up a proportion to solve. We will have the cost on the top and the number of pencils on the bottom. I will have 50 pencils on the left, and 5 pencils on the right.
[tex]\frac{7}{50}=\frac{x}{5}[/tex]
Now we will cross multiply.
7 * 5 = 50 * x
35 = 50x
Divide both sides of the equation by 50.
0.7 = x
x = 0.7
5 pencils will cost €0.7
