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:

x = (\frac{1}{100}) * (100 + 7)

x = (\frac{1}{100}) * (107)\\x = 1.07


Case 2:

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

x = (\frac{1}{100}) * (100-7)

x = (\frac{1}{100}) * (93)\\x = 0.93


Answer:

single multiplier you would use for each case is:

x = 1.07 (increase)

x = 0.93 (decrease)
