in these I have to setup the variation and solve.
1. When buying gasoline, you notice that 14 gallons of gasoline is approximately the same amount of gasoline as 53 liters. Use this information to find a linear model that relates gallons to liters. Use the model to find the number of liters in 5 gallons of gasoline.
4. A company has found that the daily demand x for its boxes of chocolates is inversely proportional to the price p. When the price is $5, the demand is 800 boxes. Approximate the demand when the price is increased to $6.
7. Find a mathematical model representing the statement.
V varies jointly as p and q and inversely as the square of s.
V=1.5, when p=4.1, q=6.3, s=1.2
I hate word problems I seem to understand it in number form. I have got a B for midterm and these are due tomorrow at 11:00 am. Hope all can figure this out. Thanks a lot!
