Answer:

404%

Step-by-step explanation:

To find the percentage difference do the following: (FV - SV)/|SV| * 100

(1260 - 250)/|250| * 100 <em>{Subtract 250 from 1260 to get 1010. The absolute value of 250 is 250.}</em>

1010/250 * 100 <em>{Divide 1010 by 250 to get 4.04, or 101/25.}</em>

101/25 * 100/1 <em>{CROSS CANCELLATION}</em>

101 * 4 <em>{Multiply 4 by 101 to get 404.}</em>

404%

The percent increase in the amount required to earn a credit over 38 years is 404%.

Answer:

Unit rates are expressed as a quantity of 1, such as 3 feet per second or 6 miles per hour, they are called unit rates.

In the given table shows the number of pictures taken and how much time it took.

For first camera;

Number of pictures (unit rate) per second = \frac{15}{3} =5 pictures.

For second Camera:

Number of picture per second = \frac{48}{8} =6 pictures.

For third Camera:

Number of picture per second = \frac{18}{6} =3 pictures.

The camera that takes picture the fastest is, Second Camera.

(a)

As per the given statement: At Davidson's Bike rentals, it costs $29 to rent a bike for 8 hour.

⇒ unit rate per dollar = \frac{Number of hours }{Total cost} = \frac{8}{29} = 0.2758620 hours

Therefore, 0.227 hours (nearest to hundredths) of bike use does a customer get per dollar.

(b)

Jessica bought 18 pounds of sugar for $10.

unit rate per dollar = \frac{18}{10} =1.8 pounds

therefore, 1.8 pounds of sugar did she get per dollar.
