An employee at a health food company is making a new type of trail mix. She starts with 10 lbs of Hearty Mix, which contains 25% dried fruit by weight. She then adds x lbs of Active Mix, which contains 40% dried fruit by weight. Let y be the percent of dried fruit in the new type of trail mix. Which function models situation?

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

Option C is the correct answer

no solution

step-by-step explanation:

there is not enough information in the problem to solve.

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
