The table shows the price for different numbers of cupcakes: Number of Cupcakes Price (in dollars) 3 12 4 16 5 20 7 28 Does this table of numbers represent a proportional relationship? Yes, because 4 times the price is the number of cupcakes Yes, because the price is 4 times the number of cupcakes No, because the price of 4 cupcakes should be $13 and not $12 No, because the price of 5 cupcakes should be $60 and not $20

Answers

The answer is Yes, because the price is 4 times the number of cupcakes because 3 × 4 = $12, 4 × 4 = $16, ...
Look at it this way:

3 x 4 = 12 

4 x 4 = 16

5 x 4 = 20

7 x 4 = 28

Your proof is true because it is x4 the next value.

12 + 4 = 16

16 + 4 = 20

20 + 4 = 24

Celia and Ryan are starting a nutrition program. Celia currently consumes 1200 calories a day and will increase that number by 100 calories each day. Ryan currently consumes 3230 calories a day and will decrease that number by 190 each day. They will continue consuming that same number of calories per day. In how many days will that be?

Answers

C is Celia's calorie count and R is Ryan's. d = days
C = 1200 + 100d
R = 3230 - 190d
Since you want to find when they will consume the same amount of calories, you set the two equations equal to each other: 1200 + 100d = 3230 - 190d.
Then, subtract 1200 from both sides: 100d = 2030 - 190d. Next, add 190d to both sides: 290d = 2030. Therefore, the number of days is eqal to 2030/290, which is 7.

Ally is making a scale diagram of her classroom. She uses a scale factor of 3 centimeters per foot to draw the diagram. The actual length of the classroom is 18 feet, and its width is 20 feet. What is the area of the scale drawing of the classroom?

Answers

Multiply 18 * 3 and 20 * 3

18*3 = 54

20 * 3 = 60

Length = 54 cm ; Width = 60 cm

Area = L x W

54 * 60 = 3240

Area = 3240 cm
