Answer: 75%
Step-by-step explanation:
Over the course of seven years, Carrie went from charging the Millards $8 to charging them $14 per hour.
To calculate the percentage increase, use the following formula:
= (New price - Old Price) / Old price * 100%
= (14 - 8) / 8 * 100%
= 6/8 * 100%
= 75%
<em>Carrie's rate went up by 75%.</em>
Answer:
30%
Step-by-step explanation:
70% of 120 is 84. So take the remainder of 70 (30, as %'s go up to 100.) and that's the percent left. We can "fact check this" the other way around as well.
30% of 120 = 36.
84 + 36 = 120.
The price of the boots have changed/raised 30%.
