Find each percent increase or decrease to the nearest percent. 1. from 14 books to 40 books
2. from 72 points to 50 points

1. 185.71% 2. 30.56%

Step-by-step explanation:

(1) Initial no of books = 14

Final no of books = 40

Increase in books = 40-14 = 26

(2) Initial points = 72

Final points = 50

Decrease in points = 72-50= 22

Hence, this is the required solution.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.
