Question

To increase and decrease an amount by 7%, what single multiplier would you use?

Answer 1

To increase an amount by 7%, you would want to use 1.07 as the multiplier. To decrease it, you would use 0.93 

Answer 2

We will solve the problem for both cases:

Case 1:

If the amount increases by 7% we have the number for which we are going to multiply is given by:

`image`

`image`

Case 2:

If the amount decreases by 7% we have the number for which we are going to multiply is given by:

`image`

`image`

Answer:

single multiplier you would use for each case is:

x = 1.07 (increase)

x = 0.93 (decrease)
