Using proportions, it is found that 66 people in the survey worked on election day.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
For this problem, the amounts of people who worked are:
Hence the total amount is given by:
0.64 x 50 + 0.4 x 85 = 66.
66 people in the survey worked on election day.

Answer:
He saved $25.
Step-by-step explanation:
- If Rob saves $5 for every $16 he earns, he is saving the folowing franction of his income: .
- Then if his income equals $16, he will save .
- If his income is $80, he will save
- Another way to understand this problem would be to think that . Then, receiving $80 is the same as receiving 5 times $16. If he saves $5 for every $16 he receives, he would save 5 times $5 = $25.

Step-by-step explanation:
I assuming it can be an equation of an arbitrary choice. And I am further assuming that by "equation" they mean a function.
so I choose a simple f(x)=|x|, then
(1)
reflected (around the x axis here)
f(x) = -|x|
vertically shifted 2/3
f(x) = -|x|+2/3
and 1/2 units to the right
f(x) = -|x-1/2|+2/3 (final answer)
(2)
f(x) = |x-4| (final answer)
