Q:
# Mr. Jones places money into two separate investment accounts. The function f(x) = 2,500(1.078)x models the value of account 1 after x years. The table represents the value of account 2 after x years. Number of Years, x 0 3 4 6 Value, y $2,500 $3,400 $3,700 $4,300 During what year does the value of account 1 exceed the value of account 2?

Accepted Solution

A:

account 1 : y = 2500(1.078)x

account 2 : y = 2500 + 300x

after the second year a1 exceeds a2

after 2 years, a1 = 5390

after 2 years , a2 = 3100

account 2 : y = 2500 + 300x

after the second year a1 exceeds a2

after 2 years, a1 = 5390

after 2 years , a2 = 3100
