Question

Capucine played a game where she earned 179 points for building 11 museums and 4 libraries she earns 4 more points per museum than per library

Answer 1

She earns 9 points per library and 13 points per museum.

Explanation

Lets assume, she earns $x$ point per library.

As she earns 4 more points per museum than per library, so the point earned per museum will be: $x+4$

She earned total 179 points for building 11 museums and 4 libraries. So, the equation will be...

$11(x+4)+4(x) =179\\ \\ 11x+44+4x=179\\ \\ 15x+44=179\\ \\ 15x=179-44=135\\ \\ x=\frac{135}{15}=9$

So, she earns 9 points per library and earns (9+4)= 13 points per museum.
