Answer:
1429
Step-by-step explanation:
Break even is expressed as:
5000+2x = 5.5x
5000=5.5x-2x
5000=3.5x

1428.57=x
Since you cannot sell a fractional yo-yo, round up to 1429
2(5+8)+101+101
Step 1: 2(13)+(101+101) =
Step 2:26+202=
Final Answer: 228
Answer:
f(g(7)) = 22
Step-by-step explanation:
First find the general form of the new equation, f(g(x)):
f(x)=3x + 2
g(x)=x - 1/3
f(g(x)) = 3(x - 1/3) + 2
You can simplify that, or alternatively just plug in 7 now and solve:
f(g(7)) = 3(7 - 1/3) + 2
f(g(7)) = 3(20/3) + 2
f(g(7)) = 20 + 2
f(g(7)) = 22
