Answer:

The percent of increase is 32.43%.

Step-by-step explanation:

Take the difference of his new score and the old score.

37-25 = 12

To find the percent change, take that difference and divide it by the new score. Then multiply that answer by 100%.

12/37 = .3243

.3243 x 100% = 32.43%

I need to increase my sales by 35% this month I’m currently at 45 sales how many sales do I need to meet my goal ?
telo118 [61]
Assume that 100% = 45 sales and 35% = X sales amount

You can create a ratio to help you solve for x

45 = 100%
x   =  35 %

Which is equal to this fraction:  (45/x) = (100/35)

Solving for X by cross multiplying and dividing by 100:
  [(45)(35)] / 100  =  X = 15.75 = 16 sales (rounded up)

You would need at least 16 sales to increase sales total by 35%
