A car’s value varies inversely with its age. Jackie bought a 10-year-old car for $2,400. Write the equation that relates the car’s value, v, to its age, a. What will be the value of Jackie’s car when it is 15 years old ?

$1,600

Step-by-step explanation:

Inverse relation:

v = k/a

where v = value of car, and a = age in years.

To find k, we use a known value

2400 = k/10

k = 24000

The inverse relation is

v = 24,000/a

At 15 years, a = 15.

v = 24,000/15 = 1,600

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25

12 cups   is the answer
