May = $24,890
May can be described as 100% (the starting amount)
We are increasing this amount by 4.9%
100% + 4.9% = 104.9%
We want a number that we can multiply by the original amount to get the new value
To turn a percentage into a multiplier, we divide by 100
104.9 / 100 = 1.049
Now, multiply 1.049 by the May sales to get the expected amount for June
$24,890 x 1.049 = $26,109.61
Expected Sales in June = $26,109.61
