Which ideas about functions do you think might be the most helpful to you in your day-to-day planning?

Functions are mathematical representation of the relationship which exists between input and output variables. Hence, an helpful day-to-day usage of function could be in calculating daily spending on food items.

F(x) = 5.60x

Hence, if 3 meals is consumed in a day, the total amount spent would be ;

F(3) = 5.60(3)

F(3) = $16.80

Hence, functions could be helpful in calculating the daily amount expended on food.

It helps in calculating the price of groceries such as fruits.

Step-by-step explanation:

Remember, functions are mathematical expressions that represent or shows the relationship between one or more variables.

For example, let's say a young girl wants to shop for 20 oranges in a mall. If we express the price using the function where;

y represents the total cost of the oranges,

20 represents the number of oranges,

x represents the cost per orange (assumed to $0.99)

Then, by means of the knowledge of function, the girl determines the total cost she to be $19.8 (20*0.99).

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.
