Jerry wants to purchase some items whose cost function is C = 3x + 5 where x is the number of items If Jerry spends between $50 and $80 find the minimum and maximum number of items that he can purchase.

As given is 

C = 3x + 5

From above relation, we get

(C - 5) / 3 = x

So now we find minimum items by putting C = 50, we get

(50 - 5) / 3 = x

45 / 3 = x 

x = 15 

HENCE Minimum items are 15.

Now we find maximum items by putting C = 80, we get

(80 - 5) / 3 = x

75 / 3 = x

x = 25

HENCE Maximum items are 25.
