Store A sells boxes of rice for $2.50 each.

Store B sells rice by the pound for $2.50 per pound.

The cost of an amount of rice at either store can be modeled by the function c(n) = 2.5n, where n is the number of boxes for Store A and n is the number of pounds of rice for Store B.

The domain of c(n) = 2.5n is all the real numbers.

For each store, drag the restriction needed on values of n for c(n) to model each situation.

Answers

Answer:

Step-by-step explanation:

Store A: Sells rice in boxes= whole numbers greater than or equal to zero

Store B: Sells rice by the pound= any number greater than or equal to zero

Answer:

66

Step-by-step explanation:

Use the equation y=x+2. y is her height, and x is her arm length. so, when 64 is x, fill in the black and do 64+2, which is 66!

copy and paste:

If she is 64 inches tall, her arms are 66 inches because 66=64+2.

Last Season, A Lacrosse player scored 41 goals in 15 games, So far this season, the player has scored 24 goals in 9 games.


A. Does the player have a greater number of goals per game this season compared with last season?

(I think it is a no. If it is not no, explain)


B. Supposed the player plays in as many games this season as last season and continues to score at this season's rate. Write and solve A proportion to find the number of goals the player will score this season

Answers

Answer:

1.) No

2.) 40 goals

Step-by-step explanation:

Given the following :

Last season:

Games played = 15

Points scored = 41

Current season:

Games played = 9

Points scored = 24

A)

Last season:

Goals per game = total points / number of games

Goals per game = 41 / 15 = 2.733

Current season :

Goals per game = total points / number of games

Goals per game = 24 / 9 = 2.667

Last season's goal per game is greater than that of current season.

B)

Current rate = goals / games = 24/9 - - - (1)

Let points to be scored this season = y

Ratio of y to number of games played last season = y / 15 - - - (2)

Equate both

24 / 9 = y / 15

9 * y = 24 * 15

y = 360 / 9

y = 40

Answer:

A=no  B=no

Step-by-step explanation:

in the first season you need to divide 41 into 15 to see how much he scored in 1 game which is 2.7333333333 continued

next you need to find second season which is 24/9 2.6666666666 continued

easy, 2.666666666 times 15 is too inacurate so do 24/9*15 which is 40 so the answer is also no
