Answer:
y = (2.5 + 0.4x) / (10 + x) × 100
Step-by-step explanation:
The total quantity of the trail mix = 10 lb
Dried fruit = 25% of the trail mix
=25% of 10 lb
= 0.25 × 10
= 2.5 lb
Employee adds x lb of Active Mix, which contains 40% dried fruit by weight.
Total trail mix after addition = ( 10 + x ) lb
Total dried fruit = 2.5 lb + 40% of x
= (2.5 + 0.4 * x) lb
= (2.5 + 0.4x) lb
Let
y = percent of dried fruit in the new type of trail mix.
% of dried fruit in the new type of trail mix = ( quantity of dried fruit in the trail mix / total quantity ) × 100
y = (2.5 + 0.4x) / (10 + x) × 100
