What is 115% of 270 ?

310.5

Step-by-step explanation:

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 270 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 270 is 100%, so we can write it down as 270=100%.

4. We know, that x is 115% of the output value, so we can write it down as x=115%.

5. Now we have two simple equations:

1) 270=100%

2) x=115%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

270/x=100%/115%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 115% of 270

270/x=100/115

- we multiply both sides of the equation by x

- we divide both sides of the equation to get x

270/0.8695652173913=x

310.5=x

x=310.5

now we have:

115% of 270=310.5

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
