Answer:
750
Step-by-step explanation:
total cost = 650

total profit = 1400 - 650 = 750
Answer:
6, 11, 16, 21
Step-by-step explanation:
To obtain the first 4 terms add the common difference 5 to the previous term, that is
a₁ = 6
a₂ = a₁ + 5 = 6 + 5 = 11
a₃ = a₂ + 5 = 11 + 5 = 16
a₄ = a₃ + 5 = 16 + 5 = 21
100 is the easiest because 1/100 =0.01
33/100=0.33
