Answer:
Earning at Long's Bank are expressed by the equation, I = -0.06 x + 8.3
Earnings at Fellow's Bank are modeled by I = -0.02 x+6.6
Where,x is the number of checks written.
now, we have to find that , at what range of checks will a checking account at Long's Bank generate more earnings income than one at Fellow's Bank.
-0.06 x +8.3 > -0.02 x +6.6
-0.02 x+0.06 x < 8.3 - 6.6
0.04 x < 1.7
Dividing both sides by , 0.04, we get
x< 42.5
So, x ∈[0,42], which is number of checks written.
