Answer:
Step-by-step explanation:
Let the cost of one soft taco = s
Let the cost of one burrito  = b
  
So  we have this system
  
3s  + 3b  = 11.25  
4s +  2b   = 10.00   (1)
  
Divide  the first equation through by 3   and we have that
  
s +  b  =  3.75         subtract  b from both sides
s   =  3.75 - b   (2)
  
Sub  (2) into (1)  and we have
  
4 (3.75 - b)  +  2b  =  10.00      simplify
15 - 4b  + 2b   = 10.00
-2b + 15  =10.00      subtract 15 from both sides
-2b  =  - 5.00         divide both sides by -2
b  = 2.50
  
And using (2)
s  =  3.75 - 2.50   =   1.50
  
  
So...  a soft taco  1.50 and a burrito is  2.50
