($cost of type a)(x) + ($cost of type b)(3x)=432.30

5.85x + 13.8x = 432.30

19.65x = 432.30

X= 22 pounds type a coffee used

Hello there,
Type B = 4.60 x 3 
            = $13.80
Type A + B = 5.85 +13.80
                   = 19.65
19.65 units = $432.30
1 units (Type A) = 22
Thus, 22 pounds of Type A was used

Hope this helps :))
