Formulating a linear programming problem

Question

I have the following problem:

enter image description here

Now I would like someone to verify whether my answer is correct or not :) Here goes: If I denote the different alloys by $x_1, x_2, x_3, x_4, x_5$ I get

$$\text{minimize}\;\;\;5x_1+4x_2+3x_3+2x_4+ 1.5x_5$$ $$\text{subject to}\;\;\; 10x_1+25x_2+50x_3+75x_4+95x_5 = 0.3$$ $$\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\; 90x_1+75x_2+50x_3+25x_4+5x_5 = 0.7$$

I'm not sure whether I did this one correct or not. Any verifications? :)

Thank you!

Your suppositions and expressions are right. Just solve it.
