What does 428,731 - 175,842 equal

(a)f(w)=50w+25

(b)Number of flowers for a given number of weeks

(c)f(30)=1525 flowers

Step-by-step explanation:

Number of flowers that bloomed, f(s) = 2s + 25, s=Number of seeds planted

Number of seeds planted per week, s(w) = 25w, w=Number of weeks

Part A

f(s) = 2s + 25

Substituting s(w) = 25w into f(s)

f(s(w))=2(25w) + 25=50w+25

The composite function is: f(w)=50w+25

Part B

The unit of measurement of the composite function above is Number of flowers that bloomed for a given number of weeks.

Part C

If w=30 weeks

Then from the function, f(w)=50w+25

f(30)=50(30)+25=1500+25=1525 flowers
