What is a function?

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable).

Explanation

According to the graph given in the question, there are 2.5 people who spend $850 a year on their pets.
2.5 people is not a realistic no. as the no. of people has to be a natural number.
But it is still realistic that people will spend more than $850 on their dog as no. of people can't be 2.5 but they can be a natural no. less than 2.5 like 1 people/ 2 people according to the graph.

Hence, Option(B) and Option(C) both are correct.

You want to buy the bicycle that is $116. You already have $43.50 saved and plan to save an additional $7.25 every week.Part A: Write and solve an equation to find the number of weeks you need to save before you can purchase the bicycle.

Part B: How much sooner could you purchase the bicycle is you had a coupon for $20 off and saved $8.75 every week? Explain your reasoning.

PLEASE HELP! I'M IN 7th GRADE...AND I NEED TO GET MY MATH HOME WORK DONE, AND MY PARENTS AR'NT HOME TO HELP MEE..THANK YOU!

Answers

A. since you already have $43.50 already saved you subtract that from the amount the bike cost so you can see how much more needs to be left to save and that gives you $72.50. Then you divide the amount your saving up every week from that. So $72.50 divided by $7.25 is 10 and thats how many weeks it will take to save.

B. Since you still have that $43.50 saved and you have a coupon for $20 dollars off . Add those together to see how much you have saved up which equals $63.50. The bike is $116 so you subtract the amount you have for the bike from $116 which is $63.50 and that equals $52.50 and thats how much more money you need. Then divide how much money needed by the amount your saving up a week, which is $8.75. So $52.50 divided by $8.75 is 6 and thats how many weeks it will now take to get the bike.
