On first week
Quantity of tomato = 25 tons
profit per ton = $250
So if she sells tomato on first week then total profit = 25 * 250 = $6250
On second week
Quantity of tomato =27 ton
profit per kg =$ 235
So if she sells tomato on second week then total profit =27* 235= $6345
On third week
Quantity of tomato = 29 ton
Profit per kg = $220
So if she sells tomato on third week then total profit = 29*220 = $6380
Now consider fourth week
Quantity of tomato =31 ton
Price per kg = $205
So if she sells tomato on fourth week then total profit =31*205 = $6355
so she must ship her tomatoes on third week i.e she will attain $ 6380 as profit.
Okay so to answer your problem. All you need to do is plug in the values that you know to a calculator.. so that would be 24,500(1+.05)^2.5
this equation equals 27,678.29. But it states in the beginning, only the money he has made on it... so you would subtract the initial $24,500 which would leave you with D 3178.29
Hope this Helps!
you would do 7.8 times 0.5 and would get 3.9. You would add 7.8 and 3.9 and get 11.7 That is your answer
If AD and DB are equal that means that this is an isoselles triangle so we can use that information and the perpendicular bisector theorem to confirm that AB is perpendicular to CD
