137.5 I took the test and got 100% 
        
                    
             
        
        
        
10% of 320 = 32
So 9.8% of 320 should be some number between 31 and 32
        
             
        
        
        
Answer:
d
Step-by-step explanation:
x/7 <2
Multiply both sides if the inequality by 7 
x/7×7 < 2×7
Then cancel out the 7s from x/7×7 to get x by itself
now
x < 14
 
        
             
        
        
        
Approximately 2 gallons will be needed if each gallon of stain and  the project will cost be $73.96 if  each gallon costs $36.98
<h3>How to find the area of a triangle</h3>
The formula for calculating the area of a triangle is expressed as:
A = 0.5bh
where
base = 15feet
height = 20feet
Area of the deck = 20 * 15 * 0.5
Area of the deck is  150 square feet
Number of gallons needed  = 350/150 = 2.3
Hence approximately 2 gallons will be needed if each gallon of stain covers a maximum of 350 square feet.
Cost of the two gallons  = 36.98 *  2 
Cost of the two gallons  = $73.96
Hence the project will cost be $73.96 if  each gallon costs $36.98
