A market research company surveyed families to measure how likely they were to purchase tiny tally snack foods their responses are shown below in the two way table by family make up,

Identify the percentage of families with children out of the total respondents. what does this number represent?

Percentage =  56.07% (Rounding to two decimal places)

Step-by-step explanation:

Let's identify the total number of families with children, this way:

40 + 53 + 65 + 73 = 231

Now, let's identify the total number of respondents to the market research:

231 + 63 + 70 + 32 + 16 = 412  

Finally, let's identify the percentage of families with children out of the total respondents.

Percentage = Total number of families with children/Total number of respondents to the market research * 100

Percentage =  231/412 * 100 = 56.07% (Rounding to two decimal places)

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this
