Question

You are participating in the relay for life walkathon to raise money for cancer research. Your parents agree to pledge $25 regardless of the number of miles you walk. What is amount of money raised m = ___ b = ___ Increasing/Decreasing/Neither Equation ___ Your club sells popcorn at the hockey games as a fundraiser. It costs you $8 for supplies. You sell each bag of popcorn for s$0 75. What is your profit as a function of bags sold? m = ___ b = ___ Increasing/Decreasing/Neither Equation ___ Ken wants to buy the new $270 game system, but he had only $15. Each week he saved the same amount of money. The table below shows how much money he will have each week. How many weeks will it take for Ken to have enough money purchase game system? Write an equation in slope intercept form that describes amount saved as a function of the number of weeks. What is the real life meaning of slope in this situation? What is the real life meaning of the y-intercept? Solve an inequality or an equation to find how many weeks it will take Ken to save enough money for the game system.

Explanation / Answer

Answer of part (f)

Here rate should be in form amount/miles but here total miles are not considered, that means given equation will be a constant function so that its slope (as rate of change) be m=0 here and y constant b=25.

And such function is neither increasing nor decreasing.

This is first answer.

Thus its equation of the form y=mx+b will be

y=25

that is second answer.
