<span>When you figure out what y is, multiply it by 7, and then divide 7y ÷ 119. Use the decimal you get, multiply it by 100 and you have the percent.
</span>and also <span>The easiest way to do this type of problems is to use the formula: </span>
<span>is/of = %/100 and substitute into the equation the values associated with each part of the proportion. </span>
<span>119/7y = %/100 </span>
<span>Now cross multiply: </span>
<span>119 * 100 = 7y% </span>
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
