(3/4)n + 20 = 65 (multiply by 4 each element in both sides)
3n + 80 = 260 (subtract 80 to both sides)
3n = 180 (divide both sides by 3)
n = 60
Or
(3/4)n + 20 = 65 (subtract 20 to both sides)
(3/4)n = 45 (multiply both sides by 4/3)
n = 60

How do you calculate a percentage change from one number to anotherj?
You take the original number. You then work out by how much this number has changed (so if the new number is bigger subtract the original number from the new number and if it is smaller subtract the new number from the original). Now you divide the difference (how much the number has changed) by the original number and multiply the result by 100.An example:100 becomes 120.The number has changed by (120 - 100) 20. It has increased by 20.To calculate the percentage change we do:20 (the change) / 100 (the original number) and then multiply by 100 (to turn it in to a percentage rather than a fraction).20/100 * 100 = 20%So, in this example, the number has increased by 20%.
