Step-by-step explanation:
Part A, Option 1 is a exponential function while option is a linear equation.
Part B, Let y=b*a^(x) be the function for option 1. At x=1, y=1100 and at x=2, y=1210. 1100=b*a and 1210=b*a^2. Dividing them both we get, b=1.1 and a=1000. y=1000*(1.1)^(x). For option 2, it's a linear equation with a function y(x)=1000+100x.
The 20 year difference would be immense. With option 1, Belinda will get $6727.5 whereas with option 2, they will end up with $3000
Look up the question on the Internet the answers will pop up and tell you how they answered it
she has 180 dollars to start off with so you want to add that to the total cost. Then she makes 60 a day sbyt only actually saves 50 of it so +50x (thats the way i see it. The way they put it in the question is questionable. Dont know if she puts off the 50 or the 10)
The amount she started off with + how much she saves from working per day = total amount she needs
Well, the difference between 120 and 90 is 30. So, for every snow blower they would make 30 dollars of profit. 30 × 200 = 6,000.
ANSWER= 6,000
