The answer is the last one
Answer:
Step-by-step explanation:
Step one:
Given data for Heather's company
Fixed cost = $5000
Additional cost = $250
in a week there are 168 hours
hence they will produce a total of 168/5= 33.6
=34 systems
the expression for the total cost can be modeled as
c=mn+f
where c=total cost
m= the Additional cost
n= number of systems produced per hour
h= the number of systems produced per hour
f= fixed cost
Step two:
c=mn+f
given that n=34, we can find the total cost as
c=250(34)+5000
c=8500+5000
c=13500
the total cost for each week is $13,500
To simplify you must factor the polynomials first.
The ratio of neon fish to all the fish in the aquarium is 3 : 4 .
In the question ,
it is given that
in Mrs. Jone's class room there are angel fish and neon fish
number of angel fish in the aquarium = 14 fish
number of neon fish in the aquarium is = 42 fish
So, the total number of fish in the aquarium = number of angel fish + number neon fish
total number of fish = 14 + 42
= 56
the ratio of neon fish to all the fish in the aquarium is
= number of neon fish : total number of fish
= 42 : 56
since the ratio is written in simplest form ,
we get
= 6 : 8
= 3 : 4
Therefore , The ratio of neon fish to all the fish in the aquarium is 3 : 4 .
