Answer:
y=-50*0.2^x
Step-by-step explanation:
the formula for an exponential function is:
y=a*b^x
what do we multiply -50 by to get -10?
-50x=-10
x=-10/-50
x=1/5
x=2/10
x=0.2
This initial value here is -50, it is the first in the table
y=-50*0.2^x
The answer would be 5.

Answer:
- 7 pounds of fish
- 18.5 pounds of lobster
Step-by-step explanation:
Let x represent the number of pounds of lobster sold. Then 25.5-x is the number of pounds of fish. The total money made is ...
4.25(25.5-x) +9.00x = 196.25
4.75x + 108.375 = 196.25 . . . . . simplify
4.75x = 87.875 . . . . . . . . . . . subtract 108.375
x = 18.5 . . . . . . . . . . . . . . . divide by 4.75
The market sold 7 pounds of fish and 18.5 pounds of lobster.
