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.

Can someone please help me answer this?
Leno4ka [110]

Step-by-step explanation:

Variable x = total number of students enrolled

495 people at the dance - 7 teachers = 488 students

4/5 = 488/x

Step 1: cross multiply

4x = 2440

Step 2: isolate the variable (x) by dividing by 4

x = 2440 ÷ 4

Step 3: solve

x= 610 students total
