Katie bought 6 bottles of milk, 7 bags of candy, and a pizza. the cost of the pizza was $11. this expression was used to represent the amount katie should pay.
6x +7x +11
based on the expression, the cost of each bottle of milk is the cost of each bag of candy.
more than
six times the amount
the same as
seven times the amount

The correct option is 3.

Step-by-step explanation:

The amount Katie should pay is defined by the given expression.

              .... (1)

Katie bought following item:

Number of bottles of milk = 6

Number of bags of candy = 7

Number of pizza = 1

cost of a pizza = $11

Let x be the cost of a bottle of milk and y be the cost of a bag of candy.

Then the total amount Katie should pay is

             .... (2)

On comparing (1) and (2), we get

It means the cost of each bottle of milk is the same as the cost of each bag of candy.

Therefore the correct option is 3.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
