Answer:

P(t)=50(1.99)^{t/12}

Step-by-step explanation:

The problem can be modeled by using the compound growth formula.

Given, Initial number P_0 of people who Nicholas sent the chain letter to=50

The growth rate, r =99%=0.99

Period of Growth,k =12 Weeks

P(t)=P_0(1+r)^{t/k}

Therefore, in any week (t) after Nicholas initially sent the mail, the number of people who receive the email is modeled by the function:

P(t)=50(1+0.99)^{t/12}\\P(t)=50(1.99)^{t/12}

vfiekz [6]
<span>At a corner gas station, the revenue R varies directly with the number g of gallons of gasoline sold. If the revenue is $44.50 when the number of gallons sold is 10, find a linear equation that relates revenue R to the number g of gallons of gasoline. Then find the revenue R when the number of gallons of gasoline sold is 15.5.

Solution:
As the question mentioned the direct relationship between the quantities, hence 
10 gallons of gasoline sold =  $44.50
15.5 gallons of gasoline sold = $x
by cross multiplication, we get that
10x = 15.5 * 44.50
which implies that
x = 68.975
Thus by $</span>68.975 revenue is obtained by selling 15.5 gallons of gasoline.
