Answer:
1. $33.75 2. 20% 3. $3,624 4. 35%
Explanation:
1. 25% of 45 is 11.25 (25 is equal to 1/4 so just divide by 4)
Then subtract 11.25 from 45 (because the tickets are 25% off)
25% off 45$= 33.75$
2. $25 to $30 (how much did it increase) We have to subtract 25 to 30=5 and 5 is 20% of 25 so he increased his prices by 20%
3. 3% of $120,800 (how much money is 3%) We have to multiply .03 by 120800 so the real estate agent earns $3,624
4. $4 to $2.60 (how much did it decrease) We have to subtract 2.6 by 4= 1.4 and 1.4 is 35% of 4 so they are 35% off
