zepelin [54]

Step-by-step explanation:

Steve 11/2 batches / 3/2 hrs = 11/2(2/3) = 11/3 = 3 2/3 = 3 22/33 batches/hr

Vondra 10/3 batches / 11/12 hr = 10/3(12/11) = 120/33 = 3 21/33 batches/hr

Steve had a very slightly faster batch rate by only 1/33 batch/hr

The value of a car is depreciating at a rate of 5% per year. In 2010, the car was worth $32,000. Find the value of the car in 20

PSYCHO15rus [73]

Data:

Depreciating: The value decrease

Rate: 5% per year

2010: $32,000

2013: $?

Step 1: As depreciating means decrease, the value of the car is decaying

Step 2 and step 3: You use the formula below to find the value of the car after 3 years (as the value is decaying the rate in the formula is substracting)

Final value: F

Principal value: P=32000

rate: r=5

Time in years: n=3 (2013-2010=3)

$\begin{gathered} F=P(1-\frac{r}{100})^n \\ \\ F=32000(1-\frac{5}{100})^3 \\ \\ F=32000(0.95)^3 \\ \\ F=27436 \end{gathered}$

In 2013 the value of the car is $27,436
