for calculate the time in hours required for the worker to produce 18 units:

Now you need to substitute
into the function
to calculate the amount in dollars she will be paid for 74 hours:

She will be paid $1,110.
B. To calculate the number of units that the worker needs to produce to be paid $3,030 , you need to substitute
into the function
and solve for T (to find the number of hours she requires to work to be paid $3,030)

Now, substitute
into
and solve for x, to calculate the number of units she produces in 202 hours:

Answer:
I'm doing the same thing and, I don't understand it either.
Step-by-step explanation:
Answer:
C. 
Step-by-step explanation:
To find the number of black ribbons one would have subtract the amount of red ribbons from the total number of ribbons. Then one would have to express it as a proportion. Part over whole equals percent over 100. The number of black ribbons over total ribbons equals "b" over 100.
X + 1 + X + 1 + X +1+ X +1 = 2X -3+ 2X -3+ X -1+ X -1
4x + 4 = 4x-6+2x-2
4x+4=6x-8
12=2x
6=x
Side lengths:
6-1=5
6+1=7
2(6)-3=9
Hope that helps! Stay safe!
