S = large shrimp and p = popcorn shrimp

s + p = 10.....multiply by -1
5s + p = 30
---------------
-s -p = -10 (result of multiplying by -1)
5s + p = 30
---------------add
4s = 20
s = 20/4
s = 5

s + p = 10
5 + p = 10
p = 10 - 5
p = 5

so there was 5 lbs of large shrimp (s) and 5 lbs of popcorn shrimp (p) in the mixture

Hi. You have to do trial and error with each of the choices to see which of those apply. They are points on the given function y=22x+32 that lie on point (x,y). Just substitute the x-and y values to the function.

a. (10,480) => x = 10, y = 480
     y = 480 = 22(10) + 32
     480 = 252 (does not apply)

b. (5,142) => x = 5, y = 142
     y = 142= 22(5) + 32
     142 = 142 (apply)

c. (8,208) => x = 8, y = 208
     y = 208 = 22(8) + 32
     208 = 208 (apply)

d. (7,154) => x = 7, y = 154
     y = 154 = 22(7) + 32
     154 = 186 (does not apply)

The answer is B and C.
