Number of people that chose salad = 81
Percentage of people that chose salad over meat dish = 27%
Let us assume the number of people on the survey = x
Then
27% * x = 81
(27/100) * x = 81
27x = 81 * 100
27x = 8100
x = 8100/27
   = 300
So a total of 300 people participated in the survey.I hope the procedure is clear enough for you to understand. Based on this method you can always solve similar types of problems without requiring any kind of help from outside.

A sold a commodity to b at 10% profit b again sold it to a at 10% loss. What does a have
ozzi
Let's answer this step-by-step.

First of all, let's estsblish the original price of the commodity as being 100%. Therefore:

Original price of commodity = 100%

Then, when A sold the commodity to B, it was sold at a 10% profit. Therefore:

Price of commidity when A sold to B:
100% x 1.1 = 110%

After that, when B sold it back to A, it was sold at a 10% loss. Therefore:

Price of commodity when B sold to A:
110% x 0.9 = 99%

Hence, A now has 99% of the original value of the commidity.

Answer:

G(x)=2x+1 , vertical stretch by 2 units and shifted 1 unit up

Given :

Original function f(x)=x

To find :

Function G whose graph is a vertical stretch by 2  and move one unit up

We use the given function to for vertical stretch and shifting up

for Vertical stretch multiply the factor by f(x)

f(x) becomes  2f(x)

so the function becomes 2x

For moving up , we need to add the units at the end of the function

f(x)+1

2x+1

Hence, G(x)=2x+1
