Do the 11% off first. 
11% of 52$ is 46.38$, then you take $40 off and your total is only $6.38
if you do -40$ first then you have $12 left and 11% off that is $10.68. 
 
        
             
        
        
        
Answer:
Step-by-step explanation:
Let number of large pizzas be l and number of small be s.
<u>Then we have equations:</u>
- l + s = 100
- 16l + 11s = 1550
<u>From the first equation, we get l = 100 - s and substitute in the second equation:</u>
- 16(100 - s) + 11s = 1550
- 1600 - 16s + 11s = 1550
- 5s = 1600 - 1550
- 5s = 50
- s = 10
Number of small pizzas is 10

Hey!
----------------------------------------------
Solution:
(5/4 = 1 1/4) and (1 1/4 + 6 = 6 1/4)
= 7 3/4 - 6 1/4 (5/4 = 1 1/4)
= 1 2/4 or 1 1/2
----------------------------------------------
Answer:
1 2/4 or 1 1/2
