Question

1) From 30 inches to 24 inches. What is the percent of change? A. Increase 20% B. Decrease 25% C. Increase 20% D. Decrease 20%​

Answer 1

It’s clearly a decrease, since it goes form a higher number (30) to a lower one (24).
30-24 = 6
6/30 = x/100
Work:
6 x 100 = 600
600/30 = 20

So there’s a 20% decrease.

Answer 2

either d or b???
