Step-by-step explanation:
A.
Cost of 4 lots for $48,000= 48000*4
=$192,000
Sales made from all 7 lots = 33000*7
= $213,000
Profit =213,000-192,000
Profit =$39,000
Percent profit =(39000/192000) *100
=0.20*100
=20%
B.
Total interest formula=
Principal Loan Amount x Interest Rate x Time
Interest =30000x0.12x5
Interest = $18,000
Monthly payments for 5 years
= 18000/12*5
=18000/60
=$300
F(x) = -5x + 1
f(-3) = ?
subtitute x = -3 to the equation of the function:
f(-3) = -5 · (-3) + 1 = 15 + 1 = 16
The unit rate of miles per hour is 28
