C, or 5000(0.9)t is correct.

Multiplying by 0.1 would not make the car’s price go down by ten percent, but 90. Hence, C is correct.

Hope this helps!

Mrac [35]

Answer: 0.87 times per second (Or 52.2 times per minute)

Step-by-step explanation:

You need to make the conversion from minutes to seconds.

Remember that 1 minute has 60 seconds. Then 20 minutes to seconds is:

$(20minutes)(\frac{60seconds}{1minute})=1,200seconds$

Find the number of times the heart beats in 1 second when it is rowing:

$x_1=\frac{(2,320times)}{1,200seconds}=1.93\ times\ per\ second$

Find the number of times the heart beats in 1 second when it is resting:

$x_2=\frac{(16times)}{15seconds}=1.06\ times\ per\ second$

Then the difference is:

$difference=(1.93-1.06)\ times\ per\ second\\difference=0.87\ times\ per\ second$

(Or 52.2 times per minute)
