algol13

Answer:

She earns $6.50 from the Smiths which is 25 cents more than she earns at the Nelsons.

Step-by-step explanation:

To solve this problem you must find the hourly rate she earns at the Smiths.  This will allow you to compare to the hourly rate that is given for the Nelsons.  To find the Smiths hourly rate divide $39 by the 6 hours she babysat there.  This will have the hourly rate.  39/6=6.5.  This means she earns $6.50 an hour for the Smiths.  When comparing the rates it is clear that she earned 25 cents more at the Smiths.

Debora [2.8K]

Answer:

$ 8300 (Approximately)

Step-by-step explanation:

Given:

Initial price of the trailer is, P_0=\$35000

Rate of decrease per year is, r=0.25

The time in years is, t=5

The exponential expression for the decrease in price after 't' years is given as:

P=P_0(1-r)^t

Plug in all the given values and solve for 'P'. This gives,

P=35000(1-0.25)^5\\P=35000(0.75)^5\\P=35000(0.2373)\\P=\$8305.5\approx \$8300

Rounding it to the nearest whole number, the price of the travel trailer after 5 years is $ 8,300.
