Answer:
Total mixture = (8x + 15y) / 100
Step-by-step explanation:
Butterfat x:
= 8% of x
= 8/100 * x
= (8 * x) / 100
= 8x / 100
Butterfat y:
= 15% of y
= 15/100 * y
= (15 * y) / 100
= 15y / 100
Total mixture = butterfat x + butterfat y
= 8x / 100 + 15y / 100
= (8x + 15y) / 100
Total mixture = (8x + 15y) / 100
