Curioustudent’s method is faster and more straight forward.
If you could understand his/her method, then using his/hers would be better.

(44+x)0.2=0.5x-2
8.8+0.2x=0.5x-2
10.8=0.3x
x=36
a)36
(44+36)0.2+(36)0.5=16+18=34
b)$34
Let x be the amount of 50 cents coins
(44+x)0.2=0.5x-2
8.8+0.2x=0.5x-2
10.8=0.3x
x=36
a)36
(44+36)0.2+(36)0.5=16+18=34
b)$34
maybe you could shorten the method a bit?
