To do this you would have to do $2.00 times 1 1/4 to get the price of roast beef and $1.50 times 2 1/2.
1)To make it easier change the fractions to decimals. 
 (1.25)&(2.5)
2) Then do $2.00(1.25) to get
 $2.50 for roast beef
3) Then do $1.50(2.50) to get
 $3.75 for turkey
4)then add them together
5)3.75+2.50=$6.25
        
             
        
        
        
Answer:I = ?, P = $500, r = 6%, t = 3 years
Step-by-step explanation:
 
        
             
        
        
        
what are the measurments of the cone, but the formula to the cone is V
v = pi times radus times radius  h/3
 
        
             
        
        
        
The final price (what it is selling for) is $796.40
The markup is 10% of the original price (the dealer's cost) , meaning that it is 10% more.
We need to find the original price.
We write this as an equation
The original price *110% = final price
This is because the original price is itself (100%) added with 10%
Plug in the known final price
Original Price * 110% = 796.40
Convert 110% to a decimal because the other numbers- such as the final price are also decimal numbers. 
Convert 110% to a decimal by moving the decimal point up 2 spaces ( basically dividing it by 100)
110% = 1.1
So it is now
Original price *1.1 = 796.40
Divide both sides by 1.1 to isolate our unknown, the original price
Original price = $724
 
        
             
        
        
        
If by base of 10, you mean that the diameter of the base is 10, then the radius of the base is 5.
volume = pi * r^2 * h
volume = pi * 5^2 * 10
volume = 250pi, or approximately 785
