Step-by-step explanation:
given:
$12.50- the price of the tshirts 
40- the tshirts they have sold
$850- the raise they need
solve:
$12.50 × 40 = $500 (the price of tshirts and tshirts they have sold) 
$850 - $500 = $350 (the raise they need and the money they have so far from the 40 tshirts they have sold) 
$350 ÷ $12.50 = 28 (the money they lack and the price of a tshirt) 
answer:
thus, they need to sell 28 more tshirts to have the raise of at least $850
hope this helps, good luck! :)
 
        
                    
             
        
        
        
Answer:
   -39
Step-by-step explanation:
The general term of an arithmetic sequence is ...
   an = a1 +d(n -1)
This sequence has first term a1=9 and common difference d=(7.5-9) = -1.5. Then the 33rd term is ...
   a33 = 9 -1.5(33 -1) = 9 -48 = -39
The 33rd term is -39.
